Just noticed today that the rewards, infusers, planar energy etc is no longer stacking with the same name items already in my bags. The cobalt and blood ember crates from before stacked just fine, but now all of the sudden they are not. Thanks!
I think rewards from crates not stacking has been mentioned a few times. One of those mentions was by me and as someone kindly explained to me there is a temporary flag added to the rewards that prevents them from stacking with previous stacks of the same item or being able to depot them, but the flag is indeed temporary. I can only assume it was something added to address some form of exploit rather than a deliberate eating of my bank space
