I am unsure if this only happens to me but several times in the last month I saw a boss enter stagger check phase and the stagger bar was no visible to me.
I know that every time this happens, if I die , I cannot observe other players. I simply don’t have the “observe” button. I will print screen it next time.
Another visual bug I have seen is Albion “jump” AoE appearing on the wrong place. When I got hit by Albion I asked my teammates if he landed on the red circle and they all said yes but in my screen the red zone was far away.
