Currently in Blood Hunt, boss fight with Jos and Valk. I have had the battle suddenly stop and reset right after the animals come charging out and the fight with the bosses resumes. It has now happened 5 times. My character, comp and the CSD are all actively fighting (and quickly winning) when the fight suddenly stops and both Bosses come into the Arena.

On the 6th try I decided to use taunt on Bosses and keep my comp by me. Got the bosses on that try with no problems. Apparently if your comp gets knocked over the edge into the lava "pit" the game resets regardless of what is going on with the character and CSD. I don't remember that happening when this first came out. Looks like a bug has crept in to this one, at least on solo mode. Just wanted to let you all know about this for future repairs.
