Yesterday i loaded up court of blades to grab the chess pieces. First game i joined right at the end with the rewards chest, wasn't able to open the chest but a chess piece popped up. Next game, i grabbed the 3 pieces from Io, Europa, and the Dreadnaught, and 1 from purchasing rune upgrades. Didn't get another from the rewards chest. So now i'm stuck on 4/5, tried doing another run but no chest piece. Anybody else have this happen?
