Immortal miniboss minions

Two minions on the "Hunting Grounds", which should be renamed immortal dodobirds, continuously revive after being downed. No additional experience is granted for re-killing them and it is almost immediate. The only way to escape them was running until I found an edge to get them caught on, as they revive and attack before a portal can be dropped.

This did not happen on my ranger playthrough, though, It happened on a sorceress using firewall + sparks through the firewall.

I've had a very similar problem with Bloodthief Wasp minions in the Sandswept Marsh.

- Entered the Orok Campfire encounter area.
- Encountered two rare monsters
- Killed them while kiting them out of the area
- Event was marked as completed on the world map
- Afterwards a group of 5 or 6 Bloodthief Wasp minions would continuously spawn after being killed.
- Killing them awards no experience.
- Returning to the area after teleporting out via waypoint (can't use portal due to interruption while casting), the mobs are still there.
- Resetting the instance solved the problem - the only way I could proceed

Similar problem in a delirious Spider Woods map right now.

The rare is gone but it's Vault Lurker and Black Spider minions constantly revive to the point i had to start expedition and have Rog babysit them.

-Stormweaver with Flame Wall+Spark
-Kitokus Current for Electrocute

Recorded it with Nvidia Overlay which also killed ingame sound :D

I had a similar experience yesterday evening with my ranger in Act 2 normal. There was a bunch of bugs that insta-revived. Since I knew that mechanic from my other char I searched around them in a big circle for the reviver -> nothing. I ran to the other end of the map but the reviving minions followed me everywhere but no rare. I had to leave the map and make a new instance to get away from them.
