The "Corrupted Soul" Keystone Interferes With Health Regen

I have ~800 HP regen/second.

With the keystone "Corrupted Soul", if I take HP damage, my health regen stops for no reason, for several seconds.

This does not happen every time! After some testing, hit damage seems to not stop health regen. Most of the times this happens with some sort of health degeneration effect involved (caustic ground, poison, dots).

The behavior resembles how energy shield regen works. Energy shield only starts regenerating several seconds after taking energy shield damage.

Edit1: This also affects the "Damage Taken Recouped As Life" mechanic. I take a big hit bringing me to half HP, the regeneration is not kicking in.

Edit2: There is no special map mod! This happens in all game mods (blight maps, heist, normal maps etc)

Edit3: With the keystone removed, after testing in several maps, this is no longer happening. I regen constantly independent of what type of damage I take and recoup functions as well, every time.

Is this working as intended?

Bump!

Sorrow of the divine turns all life regen into es regen when active. Try not using that flask and see if the issue persists.

YESS!!!
That is exactly it :D!!!!
Thank you for the clarification!
