Vexven Mucktail camp

[Madae]

So, I was camping for Vexven Mucktail, and I guess he has two potential spawn locations? On the hill inside and right outside before the bridge. I had been at the camp for several hours when a duo showed up and took the outside camp. I didn't say anything about it because I was unsure about how exactly this particular camp is split... is it considered two camps, or one camp? I petitioned about it, but of course that entire process takes too long to actually be of help.

Well, whatever the case, of course Vexven spawns on their side and they kill him without saying anything, get their loot and then just leave.

What is the situation behind this? Am I SOL and that's just luck of the draw? Or did they steal my camp without me knowing?
