I was just in a game playing the Kraken, got to stage 3 and doing very well. When it came down close to the wire I made my move when I downed 3 of the 4 players and headed to tear the Generator. Damage was steadily being taken with attacks until it got to a sliver of health left on the Generator. It then stopped taking damage as soon as I was being shot.
Is this a glitch or can the Generator only take damage when the monster is clear from all hunter attacks?
