So it started off by trying to load in to a public game. After 4 minutes of load time (starting at 7:42pm) I decided to go back to the dashboard and restart. Nope. The button did nothing. So I rebooted my 360. I had a friend (Short) invite me into his private match. Where he, another friend (Warf), and I then proceeded to play (Attempt) to play the co-op missions. First we did one with arms dealers, where the stagecoach disappeared. And we'd randomly get stuck under the map, and the only way out was to shoot your horse (you couldn't climb off), and then keep jumping till you were above ground. Then we did a mission with cattle rustlers, where our horses wouldn't return. So we herded cattle from pikes basin to Armadillo, ON FOOT. Then we did the hostage mission, which actually went decently well, Short would show he was at the start, but he said he was already done and then a few minutes later, would warp to the finish line. Then we did the river raft, where shit just got plain nutty. I fell to my death, in the 2 foot drop from the raft to the shore (not drown, fall). all 3 of us would be on shore, then we'd be under fire in the river. Just crazy shit. And the best part. Because of all the glitches, we received a grand total of 512 XP. We got 0 xp from all of them except the Hostage mission because shit just was glitch-e. And you can earn move then 500xp from running Twin Peaks in less than a minute.
 
Long story short. Wait for a patch.
