i honestly don't know why Epic haven't fixed this yet, Defenders still don't give any credit for kills, meaning you can't use them for your daily quests, or in general for solo missions you want to do, they also don't return you your weapons if you fail a Wargames match, this has been a thing since 12.00 arrived and it's kinda dumb at this point

as far as i know, this bug already happened in the past, which makes it even MORE dumb, because it means that, whatever they did to fix this, it's broken again -_-

(thanks to u/gabens_decree for the Wargames info.)
