I have one biggest bug with sex animations with sims frozen standing and having straight arms lifted
I cannot reset him, no any actions, ww.fix does not help too
the only thing is to reenter or reload this family
I had that happen once, it was windows though, fuc---ing windows 10 I hate it, it's trying to isntall some big ass update that I know won't fit on my ssd drive, so everyone once in a while it sneaks in and starts downloading 10-20 gb of shit. Anyway, it's my issue, I know the problem with that, but when that happens my game stutters and it's just bad. When I installed this mod I got that exact problem you had. Once I cleared all the crap out, and stopped the update again, everything ran great. It's never ran this good for me.
But yes, I had that exact problem, game semi locked up, and my guy was in a T pose, resetsim didn't work, ww.fix did nothing. But now it works fantastic for everything, some minor bugs, but no problems with WW so far. Just babysitting the bastard as he'll run off to paint, play chess, or video games immediately after an action. Irritating but the performance increase is worth it.
