I bought this game for 60€, I can't play since almost 1 week because of the xp bug (and also these stupid tiny unreadable text).
I want to play this weekend after a big week of work and you telling me I can't because you will not patch it before next week, seriously ?!
Just pay attention to your XP before you finish the quests to see if you're getting the XP or not. All quests I've done so far have properly awarded the XP, so the bug doesn't affect them all! Also, there are loads of things you can do besides quests. No reason at all to stop playing just because of the bug.
