The title really says it all; I'm level 10 with Zeus and I'm trying to burn a diamond in front of his alter but it just wont burn. I've tried fire and lava but when I put it out/pick it up, the diamond is still there lol. Using the Medieval MC modpack, maybe theres something in it that doesn't allow diamonds to burn but I have literally no clue

If you are using the Item Physics mod, the item entities may be sticking to the floor instead of burning
