Temple of Chaos - Poison/Bleeding vs. cannot pick up Chaos bug

Level 83, thought running through Temple of Chaos. Mobs are no problem but then AGAIN btw another of this afflictions running haywire. Getting "Poison and Bleeding from Mobs" but even at this level I could not pick up the third part for the stone altar. Mobs are respawning endlessly, poison/bleed sucked up my mana/life bottles after endless tries and then died.

This cannot be intended and if so then it is worst game design. I still expect it is a bug - Temple of Chaos is bugged with another of these afflictions. Afflictions which are preventing from playing in any ways to the end are useless!

It seems everything which has to do with an affliction damage over time has its problems in the "Temple of Chaos".

additonally:

Task / Instance cannot be deleted. It hangs. No new instance possible.
