Yeah, that guy is a real prince. I had a run-in with him in Najena near Najena's room. He was under the impression that all he had to do to claim a camp was sit AFK in the hallway outside it. He hadn't claimed the camp in response to the last camp check and it was fully spawned when I got there. I waited a bit and even tried to give him a key to the room but he was incommunicado. Finally, I just took the room. Shortly after I cleared it he returned and started whining and name calling.
I was more than generous waiting as long as I did given that the
camp rules indicate that if you stumble upon a spawned room devoid of players, you can claim it.
On the bright side, he promised he'd keep me on his list of people he wont let in his groups. Saves me from having to remember myself.
