Guardian Golem immune to damage bug

[Gorgonops]

I got to the fight with the Guardian Golem (pretty much just a normal golem as far as I can tell). The problem is, I cannot deal any damage to it. Spells and attacks just pass through it harmlessly, and AoE abilities seem to not affect it either.

I've died and restarted the game, but the issue remains. Is there anything I can do to fix this?

There is no fix. Sometimes it happens. Sometimes it doesnt. Seems random.

You can try verifying your files through Steam. Two of the golems also don't take normal damage, but iirc the damage still shows up as 0, attacks don't just ignore it.
