I've noticed what causes the "invince" bug. People, STOP MINDLESSLY SPAMMING YOUR BOLT WEAPONS. In a group this can bug the cryo pack to be un-damageable making the boss unkillable. This boss is soloable to a degree. Play with a tactic. Here's a good rundown for solo or groups:

Having a lex helps, it can break the cryo in 1 shot with a 100% barrel diffusion. Instead of mindlessly staggering him, everyone should get behind cover and one person (or you if you're a soloer like me) run/slide past him to get him to melee swing. It's VERY easy to nail a shot at the cryo while he's in recoil. Then get close to the front of him but not point blank (sliding past him only triggers the normal swing) to get him to try and use the icewave to freeze himself. Then open fire. Rinse and repeat. After he berserks he's actually easy to kill as long as you have decently high shields and ammo or good abilities. Those pipes on the arena/platform he's on can be hidden behind. If you're in the right spot (usually dead middle at a certain height, like on the yellow railing rather than the pipes themselves) he'll try and charge at you but he'll end up stopping infront of the pipes and be essentially harmless. Even if you're not at the right spot, he'll only be able to dmg you with his boomerhammer and fire wave, which you can survive if you have high shields/sentinel with Guardian. There's a good chance he'll use radial blast to knock you off occassionally, but you should be able to run back up there just fine. Again, rinse and repeat. I do this with my Ember all the time, I don't even have to use WoF or Overheat or even extra ammo packs.

It's Not A Bug, It's Damn Good Tactics.
