well it just came out. All the elder scrolls have been horribly bugged when they first came out.
It just coming out is no excuse. Bugs should be fixed and the game should be good to go before it's released. Fallout New Vegas being horribly buggy at its release is excused because 'it just came out'? Fuck that, that was unacceptable too! Granted, Skyrim is nowhere near as bad as New Vegas was, but still...quest ruining bugs should be fixed before releases.
