Why can't I hold all these chests and key fragments

Are you playing with friends more often? that tends to do it.

sometimes I go a long time with no fragments but recently I can't seem to get chests atm.

I had in total 6 keys and one chest that is pretty annoying

Lucky, I'm still at roughly 10 wins per game to get a key fragment even after reset. Still perpetually sitting on 5 chests with 0 keys. Wait a month, get a key maybe 2, then 4 more chests. lol I'm going to be rolling in chests eventually.
