This patch has nearly ruined my experience! The game ctds now, when it never did before it was patched. I'm playing on PC via Steam. I can't find any pattern in what may be causing the crashes, sometimes it just crashes when my char is just standing there, sometimes it crashes when I fast travel, sometimes it crashes when I'm entering/leaving a building.
Is there an official bug/problem report area I can go to?
Are you using any mods? It seemed like quite a few (but not all) PC users with severe problems were running mods, and ditching the mods fixed things. Might wanna try that.
That being said, others have said that elemental resistances are not working at all with the patch, and that seems unrelated to any mod incompatibility. For some people it's game-breaking, for others it isn't even an annoyance.
