invisible and invulnerable breach monsters

Bug Report ID: #3,821,077,044

breach monsters "It That Crawls" invisible and invulnerable. I think it is because the map has the modifier "chance for rare monsters to fracture"

second time I encountered this in tier 16.5 and 17

got it again on a different breach monster

Bug Report ID: #4,199,441,137

just died to this bug

I've run into the same issue twice, can confirm it only happened in T16.5/17 after killing a rare breach monster which fractured into an invulnerable mob

upup have the same thing

Upping this, had a bunch of invisible and untargetable "it that crawls" "it that watches" and etc mosnsters follow me all map, all I can see are the health bars.

Run into this the first time now. Super annoying.
