I noticed a really annoying glitch in Flood.
Sometimes it happens that teammates show up as enemies on Radar, and their name is red as well. I just betrayed a teammate because of that. The only thing that show you that he is actually a teammate is that he holds a shotgun, but I didn’t look at it until I heard “Betrayal” after I killed him.
For now, it only appears to show up for Survivors, but I don’t know if it happens in Flood as well.
This player was kinda mad at me, and it’s for a legit reason. I hope 343i will fix this soon.
