Summarize your bug I noticed this bug when i was playing. I was in game and received a t5 copper medal thing for a weapon I had already up to mastery 12 ( as i am mostly a solo/coop player, this is the limit I usually reach ) I wasnt sure about what I unlocked, so I checked my classes and collection menus and there it was : Everything, i mean every single stuff with mastery to unlock was reset to 0. Still i've got all the attachment and skins i previously unlocked. But looks like my medals for my profile are gone. Very frustrating as i finally got my 12 mastery reward on my f-35 !

Other bugs that might be related :

- XP reward bugs ? I don't know if it was intentionnal or if its a bug but even with a 100% boost, XP I earn will stay at the same range.
- At the end of the game, I don't receive any ribbons. Still XP is earned as if I had them, so likely a ending screen bug.
Sorry for poor english.
