Invulnerable Spider Mob (Essence Interaction)

Just encountered a bug about with the burrowing spider monster that is converted as a essence rare and the mobs.

In the map, the icon for the essence mob is near a ritual icon. I got near the both of them and killed the mobs in the ritual. Suddenly spiders where attacking me and I was trying to kill them but can't. I am using a spark build so I was confused why they are still alive. After running away from the essence icon, the spiders where still following me but they where bugging. They can hit my character but I can't hit them. Ran around the other parts of the map and came back and its still the same. When you try to highlight the essence crystal of the rare, Its blank. When I popped the essence crystal, thats when I can kill the mobs.

I think the character models of the spider mobs activated early thus making them buggy and invulnerable. Solution, just interact with the essence crystal and then you can kill them.

I had the same error. Map Tier 3 / Abyss
Some spiders could not be killed.

Same here, burrowing spiders from a essence attacked me as i was approaching the essence. They were invulnerable and movement was very glitchy. Fixed it by activating the essence.

I have the same issue but not from essence but as normal enemies on the "desert" map

This is also happening with the litte slugg like beetles. It seems anything that has a "burrow" ability bypasses the "locked in stasis until you triple click the boss" mode, but until you triple click the boss they are invulnerable and will 100% kill you if you can't get to the boss in time. However often times they block your ability (at least on controller) to open up the boss because they get in the way. This happens OUTSIDE of mapping/endgame as well.
