I have a chronic case of this bug. I just play the game sans sound now. I usually only get about 10 minutes of sound before it cuts off anyway.

Here you go.

Any sim who tries to use the toilet is permanently adhered to the seat until such time as a different sim in the same household moves them both out. Then they can freely move again. Haven't tried resetsim yet for this purpose but I imagine that will get them off of it.
Any toilet. Any sim. At any time. And bloody well recurring.

Anyone else have this issue in their game?

I'm not sure if anyone else has noticed this but even with all sounds muted the game music on the sims' computer still plays. I have yet to check the game simulator 2 1/2 but I highly doubt it would be different. Has anyone seen a fix for this? I hate the sound of them playing games as it is because it's overly loud compared to the rest of the sounds.

Thank you Witch! I will seed for as long as possible. 

You can do it and keep physics intact. Why anyone would do this is another story.

Exactly that. The date depends on when the file is created/changed. And since it had to recreate it, it will have the date and time it was recreated.
