Situation: The giga slime didn't drop anything yet. For crafting the slime hammer and armor, I have the ingredients, except for the slime cube, wich is still unknown for me then, and appears as a black sillouette. I re-enter the fight to get a drop from the giga slime, for crafting. I defeat him, and he drops a slime cube. The crafting menu tells me I now have one slime cube, and all the ingredients for green slime armor or green slime hammer. I craft the green slime armor. Problem: I now have the green slime armor, and have 1 missing slime cube for the hammer. Still, I can craft, and did craft the hammer, without having slime cubes. Edit: I have now crafted 32 hammers, without having slime cubes and without having big branches.
