Well this is a nice thread to tell what happened in Castle Crashers today.
Me and a buddy were running through the alien ship when we came to the timed event. After reaching the end we only had about ten seconds left then I realized my friend was stuck behind the wrong fence. So I escape and he dies (so to speak)
Oh well, I head to the next level (because only one person needs to make it). Yes, only I. See, he was stuck in the previous level. The thing is with Castle Crashers, even on online play you only see one screen that everyone shares. But we were in two completely different levels. I could still see his character right next to mine and he could me right next to him. When I died on his screen I was fine and vice versa. It lead to some pretty funny events with him flailing about the screen screaming aliens when there was an empty desert on all sides.
Needless to say this happened for a long time. Every time I advanced to the next level, he remained on whatever level he was on. So his character would be fighting invisible enemies while I would apparently be getting killed or trapped on walls.
We left and rejoined and it worked fine. Very bizarre for a single screen online game.
