Immortal rare (again)

I already reported this.

There is one monster type shoots bows with his legs.
When spawned as rare, I shoot it down, but it remains "alive". No HP bar.

It is not related to the perma-revive bug (that I also reported). This mob literally is undead and follows you like the ghosts in pack man.

(The mob that lies flat on his belly, and shoots bows with his legs)
I am now 99.99% sure that this is monster type related.

Do not thank me.
(You can send me free early access key as PM thou...)

I am not sure I made myself clear why this is bad.

My frustration doesn't come from the fact that I have to run away from a zombie for the rest of the map.

The main problem is that the mob is not considered dead for the purpose of map completion, and I have to reopen the map, and do it again without any juice or league mechanics.

Thank god that its not a valdo map ;)
