video where stack trace happens (stack trace in video is slightly diff than what i sent earlier because its using universal scheduler, but if i just use the folia api instead of universalscheduler it gives the stacktrace earlier in the issue)

what happens on normal paper ^

Because createInventory tries to create "real" inventories for an item, and thus, you created an inventory for a hopper at 0, 0, 0, in which it expects to exist and be able to open, thus, boom; you would need to pass in an InventoryHolder in order to surpress the real inventory creation

yea that fixed it, thanks
