While in squad with a friend, we took on this behemoth. We got him to about 1/3 hp and he disappeared into a rock wall. That's a basic rendering error and I thought nothing of it, until he came out fully healed. So, we made sure to back up so he wouldn't have this error happen again. Except it did. Not once more, but TWICE more. He runs into a defect in the area render and heals. Can someone fix this ****, please?
