So for my weekly challenges I had one that said get a kill with a shade turret and mangler which in an actual match I got both kills for but for some reason it didn’t count so I am wondering is anyone else having challenges bugged by actual matches and is there any way to fix this issue?
Experiencing the same issue with the mangler challenge. No clue on what to do besides hope they fix it or use a challenge swap. Would rather not use the later. 
I have seen it from time to time. For instance to get 3 mangler kills. I kill 3 people, but only like 1 or 2 would count. I find just muscling through helps, but other people find better results simply rerolling it. It sucks, its a beta, and it is rough.
