Soul Eater bug - Delve - Mob Invulnerability

As the wise sage said:

"Give a mob Souleater, and it will become immortal"

Please for the love of all things holy can someone look into this? I've been fighting this mob for 13 days now, it's hp still hasn't moved. [sarcasm]

No response on previous report. Here's a new one.

Bug details:

- Always happens in Delve, haven't encountered it in maps.
- Always Soul Eater modifier on the mob

Encountered the bug on 3 separate characters, it happens randomly, and the mob just becomes invincible for a random amount of time, sometimes forever. (at least until you leave)

As I was writing this post on the bug, it happened again - another mob with Soul Eater.

The mob takes damage up until a certain point and then it's as if the hp is "locked" into a certain amount and it stops taking damage.

In the video I throw flares everywhere to showcase it has nothing to do with the darkness in delve. (Maybe it has in some weird way, but flares don't fix it.)

The mob can still be damaged with dynamite, but player abilities do nothing.

It's as if soul eater stacks lock when they cap, but if it happens in conjunction with the monster being in darkness it also locks the invulnerability from darkness? Otherwise, it wouldn't make much sense that only dynamite can damage it.

Steps taken to reproduce the bug:

- Damaged mob for a bit
- Ran away (short range on delve light radius (75%))
- Mob chased --> when it re-surfaced it was immune to damage.

Seconding this, had the bug twice today. Dont know if this is related but I didnt encounter the same bug up until 300 depth. then from 300-313 depth i did encounter this bug twice. It definetly doesnt take any damage as one did recharge his energy shield while spammed my ice nova of frostbolts.
