Welcome!

How? It's still not working for me :/

had 2 other tasks and it still did the same though

Nope I had bloodvelds at nieve. I cancelled the task went to bank next to here and made sure i had all the items required. It would get a new task get the items it needs and stop there :/ never actually made its way into the dungeon or any other place to kill the monsters

It chooses its loadout and inventory and then just stands at the bank doing nothing?
