I am fairly new to downloading lots and have some questions that I cannot find answers to, so any help will be appreciated.
 1. In my lots catalog I have some "persons", a professor (?), the gypsy, and a few baristas. I don't know if they got imported or if they were generated when I put some community lot stuff on on of my residental lots. In any event can I safely delete them?
 2. Is it safe to delete from the lot catalog the fugly maxis made houses that aren't being used? (And just out of curiousity what WOULD happen if a file were removed for a house that WAS being used? )
3. This is the problem I find most annoying and would like to fix. I have multiple thumbnails of some of the same CC floors. Clean installer indicates no duplicate files in the download folder. This has only happened since I started downloading lots so I'm guessing it's related somehow?
 I've tried deleting the duplicate floor thumbnails, but when I try to build using the one thumbnail that is left all I get is what looks like the plywood underflooring instead of the carpet or tile or whatever I'm trying to put there. 
 Any suggestions?

Someone at MTS2 (I don't know who, and I can't check from work) has been making a LOT of transparent objects...Perhaps their method might be used to CAS a transparent sim and SimPE work could do it for already-existing sims?

I had to go Marj, since her expression made me laugh out loud. Thrice.

Anybody else have the problem of their toddler's teeth poking out through his chin? Scared the crap out of me.

I wonder too, if it's because I jack the prices up so much. Maybe at the very second they snatch up the item, they're realizing they're being swindled. I'm selling platters of baked goods at $1000-$3000 a pop. If that's the case, I don't really care. I'll take the killer profit over the high business rank. It's at level 6 right now anyway, and it's only been running about 4 or 5 sim days.

According to the guide, customer loyalty is lowered by seeing an out-of-stock sign - amongst other things.  Could be that your particular grump was affected by any number of the factors listed and the out-of-stock sign tipped him/her over the edge.

I've had customers who must have major PMS given their negative attitudes, no matter how hard the owner works to make them happy.

It isn't a hack thing - just the way the game runs.

 

I've only had two...  the male I called servo, the female I called servette
