From what I know so far:
Quest and vortex both affected, this is with zel/karma/honor on or off.
First fight/win you get negative karma or zel (as in the screenshot). I think you actually get the real amount but it doesn't show. It let's you continue the game.
Second fight/win, you get an infinite exp loop. You actually get the real exp but the game just constantly adds exp to the bar till you're forced to restart the game.
*Edit: By first and second fight, I mean that literally. The very first fight in a quest or vortex you win, you get glitched but can continue. Anytime you have another fight, then you get the "second fight" glitch. (Happens repeatedly after a app restart).
It was working fine prior to joining a guild and contributing, which I did all at once.
This is the same with autowin or fighting through the entire quest/vortex.
