After some digging on Ark's reddit and such, I think I coincidentally was level 95 when "Use singleplayer settings" was switched off, and it's corrupted my ability to gain xp as well as a few dinos I had at that point.
Wondering if it's happened to anyone else and if creating a new character fixes it?
Ok. It's a Graphics bug. Can confirm we have levelled today.
Unrelated: I'm only gonna be on sometimes until the windows 10 version, please don't wipe D: Controller is gonna give me a repetitive strain injury.
Well, the xp number is rising, just not the bar... so, a graphic bug? I guess it feels like I'm not gaining levels because I stopped power-building so the xp is trickling in comparison, plus what you said.
I thought I was stuck at level 85, too. I opened my character window and it says I am gaining XP at a constant rate, just slower. I think it's just pretty slow 80+. Could also be a bug, though.
