Third and final issue for now.

Using the Alchemical Mixer to create Antimony using the incorrect amounts of ashes creates alchemical waste as expected, but it creates two, one which I can pick up, and another ghost copy which just stays in the world and can't be interacted with.

They disappear when the world is reloaded, and if a block is placed over them they don't get pushed out.

I will say that I have a lot of other mods running, sort of as a personal modpack for me, so while it could be some incompatibility issue, I can never really be sure.

Anyway, that's the three bugs I've found so far with Soot. Sorry to post so many in a row.
