Void beacon seems to be bugged!

Hello!

Was randomly leveling with a new char ( lvl 38 occultist ) got my first ascendancy and was happy that i could get rid of the pesky life regen mobs with ease!

Then suddenly in act 4 ( kaoms map) encountered a life regen mob ... it was a red totem which tps and uses lightning skills... was happy that finally will get rid of this pesky mob... but suddenly i noticed how his hp began to regen ... rather quickly... id say like it normally does. Was confused at first and thought that the 100% reduced health regen (from Void Beacon passive )meant that it reduced the hp regen only in half (like from 5% per sec to 2.5% ). I was fighting face to face so its not the problem of me being far away... i then began to see if thats the case and proceed to run away to see if theres any difference ... and there were none!!! I then went back in town to purchase a frost bomb ( which states that it inflicts 75% REDUCED health regen (same wording as Void Beacon passive)) to see if something happens... and to my fear it did !! The monsters hp bar barely regened!!

The mob is from campaign so no mods other than the lamp ( the mod that gives +20% all res) minions explode and death and thats it... Now im super confused and dont think will continue to level further... I hope i was clear enough!

P.s.: Sorry if there are any mistakes. English is not my first language! Have a good day ya all!!!

I have had no problems with void beacon this league on my cursebot. Probably a case of leech but impossible to tell without a video.
