If that happens to you, ask fammembers to loot every single item that dropped in last wave. Thing is - only ONE item causes that bug and when someone picks it, it get fixed. It will fix your problem for now. But it will keep buggin till you relog. As the guy who did about ~200 lods, i am for real. 95% of time you can fix camera by picking items with alt or getting someone else picking it. Other 5% it just super crashes and dies.
sometimes screen problems can solve with changing screen solution too. like old blue screen(still exists or not idk) keyboard shortcut was alt+1 alt+2 etc changing old days idk now changed or not. Try it.
