While in my inventory, lava buckets have a plus sign on them like the shulker boxes do to do the quick add function while I'm holding an item with my mouse. Doing the right click function in the same manner as you would do for shulker boxes, effectively deletes the item. I've never seen that before and I didn't read about it on the features page so I figured it might be a bug and I almost deleted some items instinctively going to add them to the plus which I thought would be on a shulker box, but instead it was the lava bucket.

I apologise, I did more looking and found it's a feature when checking the discord. Sorry to waste your time. Thank you for the mod and the excellent work. You're great.
