For some reason, when I finish the drinking contest, I don't blackout. No "Quest Complete" comes up, and I have no mods installed, this being the normal game on Xbox 360. I find it very agitating, even more so given the fact that I've attempted it multiple times. The quest starts, but no objectives are given after the contest. Nothing happens and I'm still in the tavern, as is Sam. If someone could help me with this, it would be much appreciated.
