the Community patch is now at version 0064 and so far it's really good - I haven't come across any language issues yet as I believe it doesn't effect localisation (I play in english) and it's really nice to visit places you've visited many times before and suddenly come across new quests.
It's comes as did the Xmas patch with exe to apply the patch and one to remove it - this works well so you can actually play sp with the patch , remove it and then go online closed.
Weirdly I've also noticed one other thing with my own game is it's appears to be more stable for me (I'm on win 7 x64 , using Elite grapghics and physX - so worse case scenario) with the patch applied
