As the title said, while doing Garmoth world boss, sometimes it shows message saying my karma dropped (around 5k each time). Also for some reasons, after Garmoth is dead, although my Alt+C is not turned on (I checked the force pvp button to see if it's on or not), everyone's name keep changing from normal to red then back to normal rapidly for like 10s. It only happens at Garmoth, I don't have this issue anywhere else.
Anyone knows what the problem is or just an ancient bug that's still not fixed? tyvm.
