I don't know, I thought there was something wrong with my models But here's my block registration code: And here's my 'CustomBlockSlab' Class:

Hi. I wanted to add slabs for some blocks, everything works fine, except if I make it a double slab, and then jump on top of it, I sink through it and the game crashes. I've looked online but I can't find a solution. Log output: My json files: Thanks in advance. EDIT: This is not just for double slabs, it's also for upside-down half slabs EDIT 2: Slabs don't save properly in the world either, if i place a normal half slab, then reload the world, it becomes an upside-down half slab
