Me and my friends set up a private server and ran through a dungeon and we found once we fought a Tracking Golem, it pulled all of our attention and caused all of us but one to disconnect, leaving the dungeon. We think its the person who gets seen first stays in the game, because it was always the one who led the way through the dungeon, which got rotated everytime, meening different people disconnected each time.
I think the coding problem is that it tries to attract the camera of all players, maybe changing that to one player would fix it, like the player its attacking.
I don't want to sound like a know it all, just a suggestion
