Bug Whit The Lech Kril

[PoRo_FIN]

!SPOILER ALERT!

 

So i want normally in the mission to kill kril whit my brand new frost prime. I had done it couple times before and ran to the boss like usual. After we got him to the first damaging phase i thought that i'll use avalanche to wipe him faster. But after that the things started to get weird. The shields of krill didn't regenerate any more and he took only hits up to 12 or something. So i tried to use the avalanche again and boom heis shields were back but we couldn't kill him bechose his back back wasn't taking damage (I emptied my Boltor and despairs to him)

 

I think it has something to do whit the freezing of the krill. Hope you can fix this and keep re-making the bosses.
