Guild Wars 2

Alas I have no screenshot of this, but what happened was that my character leveled up (or gained a skill point really since he is level 80 already) at the exact same time as he would be downed (by an NPC in WvW if I recall correctly), which lead to something weird.

My character got the “insta maxed health” associated with the level up, but the game also seemed to consider him downed. I got frozen in place and could only use my first 4 skills, as if the game thought I had only the downed skills equipped even though I was looking at my normal skillbar. Naturally this lead to be getting downed “for real” (not defeated which should have been the case if it was only a display issue) in short order, and then I could use by downed skills normally again.
