Essence Monster Didn't Drop Essence

Specifically it was the falling giant skeleton in valley of the titans, took a bit to spawn after clicking the essence, and when it died it dropped absolutely no loot. Essence of the Mind was the essence that was supposed to drop.

I also had the same bug in valley of titans. Found 2 essence's spawns on the same map. First one didnt pop monsters at all, second didnt drop essence on rare monster death.

Happened to me as well, to be specific in The Titan Grotto map. Cannot say what essence that was unfortunately, but can confirm essence monsters sometimes just don't drop essence.

I had the same issue.
The same Giant Skeleton mob but mine was with an Essence of the Body.
Hammer of the Gods absolutely deleted him for 0 drops.

same here it was the last rare in the map, dropped no loot

This happens to me frequently to be honest. I noticed few times for some reason monster rushed to me and exploded and dropped nothing at all. Anyway, annoying.

Happened to me aswell, reference ID 143 013 566

I experienced this with the terracotta fanatic in the titan grotto.
The rare monster exploded and did not drop essence. This might be a bug regarding that mob type not being supposed to be able to spawn as rare normally, but somehow can spawn as trapped in essence.

I had this also on a t1 lost towers, it only dropped some stacks of 1 gold. bug ref #1618541183

Dont recall the monster type, but happened to me as well with a T15 oasis map
