So I was playing as Jack in horde last night on wave 44 or so. I hijacked a scion and starting mowing down swarm when I saw a teammate needed reviving.
I was also getting blasted with the crying cannon so I used Y to cancel the hijack and go save my team mate
From that point on my Jack was being frozen and injured alternately until the end of the game, it never downed me but I could barely move and left me near to death the whole time.
We still finished all 50 waves but nothing I did could release this cycle
Just another one for TC to look into
