Recently the boss in the PVM room keeps disappearing when he is almost beaten - just goes "poof". Happened today with the Slasher. Anyone else experience this?
Yes, that's a known issue.
Its an issue with the timers, the boss will only remain there for a set period of time
Had a feeling it might be a timer issue - or else The Slasher just doesn't like me. Guess I should stop messing around and kill it faster LOL
if you notice a boss that noone have killed the spawn for, be cautios
