Jack Bugs During Horde

Has anyone else had issues with Jack? If you get hit with a Cryo cannon many times u don’t unfreeze EVER. Even after a new wave starts it goes away and comes back unless you kill yourself. I also had an issue when using Hijack on a scion I was unable to Zap stuff anymore. The enemies would stop and convulse but no animation of electricity or damage was being done. Until yet again you killed yourself. The Frozen map was the worst as anytime I got froze it was permanent. Really makes you not want to play the character when theres that many issues with him.
