Gorian, the Moving Earth stuck in itself

While doing an Waystone 2 Map i encountered a Bug that doesnt let me finish the Map.

The Map spawned with a Boss that spawned twice (dont know if thats normal for that Boss because it also happened another Time with that exact same Boss) but this Time the Boss got stuck in itself and got invincible.

Nothing i did dealt Damage to him any more, and even when he had an Attack Animation, he also dealt no Damage to me or my Minions.

I Tried to clear the Whole Map first (also finished the encounter with Gwennen on that Map) and also tried to go Back to my Hideout in order to Reset him but to no avail.

Here is a Screen Capture i took:

Also encountered the same bug where a second one spawned. The first one stopped taking damage, and after killing the second, the first one just sits there with no aggro in either direction.

Same here

Same here, Gorian stuck in itself and not killable :/

I managed to unbug it! You dodge roll into/through him a few times and he starts attacking again!

Same here, stuck on itself, cant complete map :(

Dodge into it, dosen´t works.
Stiil stuck in itself - waystone level 15.

FOR ME IS WORST. It simply does not spawn at all.
