At last I decided to install latest official patch to test it one more time.
the bug with blackened tenant's object (
http://www.insimenator.net/showthread.php?t=97800) is not in every block fortunately.
So I guess The patch is OK for now.
I have another strange BHAV with visitors on community lots. Some of them arrive and just stand like a dummy with nothing doing but their needs are getting low. Some of are OK they are talking, playing etc. Some of them are just standing on one spot. No errors occurs (I always play with the developers cheat)
Do you have something like this too?
