I got the original DLC bug after going into Vault 3 about a month ago. Yesterday I downloaded the patch(es) and carried on from a pre Vault 3 game. I cleared a few areas around Vegas, saving and reloading as I went just to check everything was working ok (which it was), then went back to Vault 3 (which I am sure had a different layout last time I was there), and cleared it out. When I came to load my post Vault 3 game today I got the DLC error message back again. Has anybody else had this after the patch? I have managed to reload an old game and will just steer clear of Vault 3 in future.

This game is just a JOKE. And so is Bethesda. I tell anyone who asks me not to waste time and money on this P.O.S. And the few who have gone out and wasted money on it after I told them not to have told me they should have listened to what I said...

Mate, you should be aware that the patched are fully effective ONLY on games started after the patches. The patch may fix some minor glitches on already started games, but to enjoy the complete effect of the patches you should start a new game.
