If you've loaded up Skyrim today and installed patch 1.2 you may have noticed more issues. 360/PS3 players have reported dragons flying backwards and resistances no longer working correctly. PS3 players are also still experiencing some lag issues. Whereas the PC version is working fine. If you're lucky enough to have not installed it yet, don't accept the patch.
Personally, I haven't played it today, so I'm safe. I'll reject the patch and play offline. I was pleased to hear I'd be able to play straight off the HDD now, but oh well, guess we'll have to wait until the issue is mended by Bethesda.
