Minions from Essence attacking while essence still caged

I cant tell if this is from an essence or not near by, but a bunch of untargetable spiders are attacking from below ground and have a rare skull on them via mini-map.

I will attempt the essence, and update.

100% was minions or spawns from the essence with shroud walking

thankfully this time was not life threatening

Same. Mastodon Badlands. Sabre Spider. Some trapped, some move and glitch around, untargetable. Become targetable when Essence monster activated.

Hi,
Encountered the same bug. Glitchy untargetable spiders that were damaging me and were only killable once I activated the essence not too far from there.

Mud Burrow, Flesh Larva.
