yes it is hell we have the same bug.. he just cant get killed

same here happened twice now , its when he changes to asceneded 2nd time

If anyone have bug on story mode in act 3 i help you, just invite me in game, emptyyourmind.4349

Yeah same thing for me, thou it happens mostly during phase 2 or phase 3. Kind of annoying. He just stands there all immortal like :)

I just got upto this part too and it's the same bug, Phase 2 2nd time Ascended form :(

Same bug. i can't kill heimlock.

Same bug. Tried the "strat" to kill him (not doing damage after he became stun in phase 2), but 3 times out of 4, he froze. Hope a fix will be realesed soon.

EDIT : got to phase 3 and... freeze...

Now it worked!

I slowed down my DPS on him whilst he was transforming and then i also kited him around more so he did not transformed right next to a pylon, not sure it was because of that but it worked :) if that is not working then just keep on pushing like it did do not lose hope it will happen.

not possible to kill him....

It's apparenttly adding dots to him when he goes to transform that glitches him out. My build is based on them so I'm having a hard time right now as well. Hope they fix this soon because its really annoying.

Same issue :( very annoying and i hope they fix it SOON.
