Glitches from downloads...

I downloaded a whole bunch of stuff yesterday, and it caused my Sims to be a bit off. If I try to get two sims to relax on the same bed or get in the same hot tub, they won't. Instead they'll just stand there, but flicker and twitch around a bit, like they're trying to move but can't.

I think that what happened is I installed some stuff wrong. I downloaded the love bed and a few other things that include custom animations. I'm guessing that there are animation files that come with these, that I should have put in a folder other than downloads? I'm guessing it's something along these lines, because it was after trying to use a love bed that these issues started cropping up.

The only extension I have is University, if that makes any difference.

As a side note, where do I find the anti-nude-blur patch? I thought getting nude meshes and skins would do it, but apparently not.

thanks.
