Campaign - Full inventory and box disappearing

Hello @Sarah247, it’s the 2nd time this happen: I had my inventory full after some runs in campaign so I went to the workshop and fused some items; at this point a prompt window should appear telling me I can finally claim my unclaimed box, but nothing appen.
If I quit the workshop I cannot see any unclaimed box going to the relative section, it just disappear.
That happen only in campaing, if I’m full by chance while doing arena or while buying grey boxes, unclaimed section work as intended.
