Steps to Repeat:

1. Place Giant Chance Cubes
2. Move part of the chance cube to another location
   -- Mechanism Cardboard Box
   -- Blood magic Teleposer
3. Break original Chance Cube
4. Place moved chance Cube
5. Break the moved chance cubes
6. The moved pieces do not break, spawn rewards at original locations

Profit

Well..... I ain't even mad about that. None the less i will fix this xD

Until then, Mek has a cardboard block list, what would the name need to be to in the blacklist?

if you are asking for the name of the block it should be chancecubes:giant_Chance_Cube

The full chance cube in a whole is chancecubes:Compact_Giant_Chance_Cube, So each section of the 3x3 block chance cube is chancecubes:giant_Chance_Cube?

chancecubes:Compact_Giant_Chance_Cube is the singular block that you can place down that then spawns in the giant chance cube. each block in the 3x3x3 giant cube is a chancecubes:giant_Chance_Cube
