The weirdest thing just happened on infinite

So I am trying to finish the ultimate from last week before it changes today and one of the challenges was getting top 4 in rumble pit and while I was in the match my screen got frozen and I couldn’t tell if it crashed or not so I restarted infinite and the challenge for it is gone? Like idk if the screen freezing glitched my challenge or something cause it was me at 19 and the 2nd player at 8 kills so I am confused.

I have had strange things happen with the challenge system before too. Sometimes to my benefit and other times it screws me. I clearly remember having one challenge to get a kill with the Hydra and I finally got my hands on a Hydra at the end of the match and couldn’t get a kill but when I went to my challenges it had disappeared as though I completed it. Another time I had to get a kill with the skewer and drilled some guy straight in the chest in a match and it didn’t count it…it does weird things from time to time.

Yeah just I had the weapon challenge glitch before just hope the bugs gets fixed
