hey dude, your mod has some problems, one of them is the name of the blocks that appear in the form of IDs instead of titles, example: lava.sponge.item
make it so that when you put it in water is makes a steam sound and turns back into its original form,
like wet sponges when you place them in the nether
Actually, since we can craft them it's fine to not be able to reuse them. If you have a magma and basalt farm, it's easy! Maybe if the sponges generated naturally as rare blocks in the terrain or were part of structure loot like bastions or ruined portals, adding a reusability feature would be fine, and they wouldn't have a crafting recipe.
