Yesterday while playing the .222 version, I had a round where some allies appeared as enemies (ie. no emblem over their head). I actually killed one of these allies and got no TK message. I also saw what appeared to be some enemies killing each other, with the tk message and all, but in reality it was actually allies and enemies killing each other properly.
Everything was back to normal the next round. I don't remember for sure any details that could help recreate the issue. It might have been the 2nd round, after the scrambling of teams, and I might have been fiddling with my equipment or the character abilities screen... but I'm not 100% on that.
