I have the same problem.  I don't really know if it is a fix or if I was just lucky but after I played a lot in which I place items from the inventory, I place some of those items back in the inventory because I decided to move them again in a new house, when I place the inventory items in the new house I notice the items were back to normal, I could place them against walls. 

So I wonder if by placing some of those messy items back in the inventory, save and reload the lot and then place them back, if it fixes that problem or not.  It could have been luck since it only happened once and I did not had a chance to test this again but I still wanted you to know in case it could help you fix this problem.

Problem you have seems weird to me, I resetted my neighborhoods by deleting the C;/mydocuments/eagames/thesims2 folder, I started from there and in my downtown I can both "shoo" poker players and quit playing poker.  I don't have hacks or any mod in my game.  If you have some, could one of them be causing this problem?  Or maybe having boolprop on could make this happen?  I am just wondering why I can and you cannot.

This should be fixed in both University and Nightlife patch according to MaxoidTom.

For #4:  Turn on the stereo action cannot be cancel either if a Sim decides to do it on its own

For your #9, I resetted my game after I install Nightlife (by deleting my Sims2 folder in c:/mydocuments) and I no longer have multiple Barista created.  I have seen 3 different ones and they keep coming back (I took their name down and brief description to make sure it was always the same ones).  I don't know if it is because I resetted my game that it was fix but it is ok for me now.  I did not check to see if it would be the same ones in the college neighborhood but I am pretty sure it will be the same ones.

I don't know if this is a bug but the new "anger" feature is annoying for people with University.

I went on a downtown lot and one joybuzz another Sim and he poked it, for 5 minutes they were poking each other and it ended in a fight.   This happened to me 5 times in the game and I could not do anything since I had no control on those Sims.

Could this please be adjust so if a Sim throw a balloon at another it won't finish with a fight.  Are my Sims doomed from time to time to hate every Sims in the neighborhood that don't have a nice personallity?

I don't have any custom stuff at all in my game, just MaxoidMonkey objects, I completely resetted the 3 pre-made neighborhoods by deleting "theSims2" folder in "mydocuments" after I install Nightlife to make sure it was a fresh start.  I will try and delete the stereo and replace it with a new one to see what it will do... sigh.... Thanks for your help, by the way I just love your picture 

These are a few bugs I notice in Nightlife.

- At home, my Sims do not have the option to dance together anymore when the stereo is on, it was a great way to build relationship.  Also I don't know yet if it will make it impossible for my teens to get the "dance scholarship" (which was one I really like to get them) since they could only get dance points by "dancing together" with another Sim.  

EDIT:  A little update about this bug, while playing the "Smith" family in Strangetown, adult and elder have the option to dance together, but the teen did not have that option to dance with either the adult or elder, I have to check if the option is there if another teen is on the lot, it is still not normal since Teen were able to dance with adult and elder before I install Nightlife.

These are University bugs I wonder if they are fix or will be fix with a patch:

- The piano sounds in college take over all the other sounds except music, so I cannot hear what my Sims are saying to each other while they are either on a date or on college community lots  I decided to delete the piano on all the downtown lots it was on and in college too).  I sure hope this will be fix since it was the same thing in University and it was affecting all the musical instruments.

- There is a bug with creating barista expresso tender, everytime I go on a community lot in either college or regular neighborhood the game keeps creating new ones, it takes a lot of character place.

- Finally, the game did not create new townie teens even if I send them all to college.  Children that change to teens have no friends to bring back home from school or work unless I create teens myself.

Well I did put a question that was not answered but while I was playing my game I was wondering if this was ever notice by anyone (and this is not the question that as not been answered  ).

In Sims 2, when I saved and then return to a lot in which a ghost was, well when I reload it was always there waiting to scare my Sims.

Since I install Univerisity I notice that the ghost that came in Pleasantview will not stay if I save and reload a lot, now this mostly apply on the Goth house lot, Caliente and Dreamer lot which are all Maxis made.  I did not really notice if it was happening with the Sims that I created and died since I recently resetted my game and it was also happening before I resetted it.

Now the strangest thing is that it does not seem to happen in Veronaville or Stangetonw (though I am not a 100% sure about Strangetown), I save lot and the ghost are still there when I reload the lot.

What I wonder the most is since almost all of the Sims that died in Veronaville that were Maxis made can be brought back with the resurrect-o-nomitron but this is not true in Pleasantview nor Stangetown since only the former Dreamer wife can be brought that and I think no Sims at all can be brought back in Stangetown, well would it explain why the ghost just vanished if we saved the game at 3am (Sims time) and reload iit?  

It is definetely not a major bug but it could explain why some pre-made Maxis Sims can be brought back to life and others can't.

Well I don't want to speak for everyone in here but for sure it is really really appreciated that you took the time to read our complaints, questions and worries.  With all this experience, I now finally have the impression that I can make a difference with Maxis. Thank you for listening to us, taking notes of our requests and trying to make the programming of the game differently so it can make players happy.    At least for the 1st time in months I do honestly believe a patch for Uni is on the way... Now let's hope it won't takes months before we get both Uni and Nightlife one's  

What if it will motivate us to send a teen to college and will give us another reason to make it go through all that part of the game?  It would defenitely help me making that decision if I would see such a want!  Already Elders have impossible LTW to fulfill (when we create them in CAS or if we install University after they were elders) like becoming a "chief of staff" when they are not in that career track and by changing carreer track it won't help them anyway so what difference does it make if teen would have LTW that cannot be fullfill.  Can the player decide by themself if they wish to fulfill it or not, LTW are random and personally I always save before my Teen age so if I don't like what I see I reload the lot and go to the birthday process again so the LTW will be different.  And now in Nightlife we have a new aspiration reward which permit us to change our Sim aspiration so I guess the LTW will change too, so why not include them now.

What I mean is that you lock the "make out" want and right away choose in the kiss option "make-out" so both will be fulfill one after the other.

If you lock the "make out" want before you make them kiss, both will be fulfilled, it always worked for me.  Of course if you have another very important want locked it will not help.

After I send all the townie teens in college I notice the game did not created new ones so my newest teens were not able to bring back friends home from school or work and meet other teens unless I created new ones myself which is very annoying, will this be fix?

Everytime I go on a community lot either in college or regular neighborhood community lot on which I put an "impresso express-o-matic" I notice the game created a new NPC and from time to time I notice I must have 50 of those barista, has this been fix since it takes a lot of space in the character folder and will there be a way to delete the extra ones we had by mistake.


EDIT:  Oh Well, like usual on chats my questions are never answered....  so I will type them differently in case it helps!
