Insta kill essences

There is a bug where you instantly can kill any essnce mob. There are a few conditions for it to happen:
1. T17 map mod "incresed monster max life"
2. Meatsacks
3. Scarab which imprisons all monsters on map
4. your imprisoned monsters should have 4 or more essneces on them
As far as i undrestood this combination scales to realy large numbers mob hp and when you release them it makes their hp = 1 and you just instantly kill them.
