So I've encountered this glitch a few times, pretty much always in a boss fight on BO6 when I would try to use Reign Drops, however this is the first time I've encountered it in BO7. Not sure if you can hear in the clip, but I am spamming 4 to use the Support Group GobbleGum that is currently in my inventory, however it just makes a sound like I am not allowed to use it. I tried progressing rounds and swapping my gobblegum packs, but the only way to fix it was to save and quit. Its not like its a huge issue, I was just wondering if anyone had encountered it before as I've never seen anything for this specific gobblegum issue.
