We (me and henniferbob) were messing around in the Dragon Sea MP level today, and I had a funny glitch happen to me.
At the start of the level, we stayed at our spawn points (very far from each other) for a few minutes to chat while checking out the idle animations.
Henniferbob then went ahead to explore the level, and a short while later I also flew in that direction. It's a huge shame I wasn't recording at the time, because what subsequently transpired was pure comedy gold:
I found henniferbob still idle at her spawn point, so I went exploring in the other direction. We chatted a bit, and then she asked me where I was at the time, so I returned to where she was a few minutes before. Still sitting there, I see.
That's when the insanity started to set in, since the ensuing conversation was becoming increasingly disjoint from what I was seeing right in front of me.
Finally I had realized what happened, right after she asked if I can see her shooting fireballs around - while she appeared to be still sitting idle at the spawn point, with no fireballs anywhere in sight! So that was clearly a duplicate of her...
But when she flew over to check out her clone, it suddenly vanished right as she came into view
