Mankrik Horde - happened on Frostberrie and Berryblessed and probably the other characters too
When picking up the quest you get 3 wisps. It looks like one, but it’s 3. You only notice when you get close to a portal to close. Then when it’s closed, the next wisp picks up the spawning portal unless you run away fast enough. Any other portal you would pass that’s free they’ll go to as well tying that portal up.
The only way to stop it is the run back to entrance with all the firekins chasing you and turn it in before your 3rd tries to close the portal.
