@rosemow I already found this thread from googling, but the bug seems to be quiet old by now, I hope it gets fixed soon :o
@Juudia the bad thing is, my sims were supposed to be friends with their neighbors, but its nearly impossible because the relationship drops everytime they complain, no matter how my sims react. Now I always need to change the relationships back with MCCC.
I also noticed that they only complain when my sims were the night out and just came back home. The not-animated elevator can't make this much noice, right? :D
Additionally, I also had a bug where my sims couldn't complain when THEIR neighbors were noisy, there simply wasn't an option on their door, I need to use a mod that disables noisy neighbors now because my sims couldn't get any sleep. I wonder if these two issues are connected to each other in some way?
