Legend!
Nice find, seems like it was a web only issue - it should swap the items when you drop from Storage to Inventory, and the inventory is full, I've deployed a hotfix to fix that, so it shouldn't happen again.
In the future will be posting Desktop builds as well (already got a private steam preview desktop build, just not a desktop itch version), runs are all persisted server side so any crashes shouldn't change anything luckily
I considered adding card upgrades, but paused that idea for now to try and make it easier to balance/design, but might revisit it in the future.
v0.4 (coming soon™) will be somewhat radically different as well, thanks for testing the alpha in its current rough condition!
Appreciate the feedback and support, its super motivating for me, as appreciation as my first ever reviewer, will name a character Babu :D
