Putrid Coating node not working (Summon Bone Golem)

The node states that it has up to a 50% chance to grant you a stack of the putrid coating buff when hit. No matter how many times the golem is hit at max effect, no visible buff appears for the player. Report going back many months state the same issue so im assuming this is global issue.

Would love clarification on if this only is a visual bug or not working at all as im planning on taking advantage of this node.

Also thank you Last Epoch team for making an awesome game!
