Shard no Stack! :(
Hi GutinhoFox!We are aware of this issue and currently have this listed in our database. We're working to have this fixed in the next couple of updates. Thanks for improving Dungeon Defenders 2!
Hope to see this fixed soon
This is still a bug for me, I can't tell if it is stacking but not showing the stack count(or it's so tiny that you can't ready it) or it just doesn't work.
