Lags & Invisible, Frozen & Stuck Sims --> Post here if you have the issue.

I too have had trouble with my Sims fereezing, disappearing, or ending up in a lump of several Sims (especially when everyone leaves school at the same time). This has happened since I patched my game to install LN.

I've uninstalled LN (thought this may remove the bug and I didn't really enjoy it -- constantly haunted by vampires who were nowhere in sight and always losing frewindships due to rumours), but I can't get back to the pre-patched version, so the problem is still there.

Is there a way to go backwards to an older version of the patch?
