I'm having some issues creating the block rainbow generator, I'm making this post to ask if its banned? I checked the banned list and it wasn't shown. The reason I'm having some trouble is because i made the bottom half with no issue, but when it came to making the top half i made the required generators put them in my crafting grid and when i pulled the top half out it switched into a bottom half. I did this a second time to confirm i hadn't messed up but it once again switched. so now I'm sitting with 3 bottom half rainbow generators and no top half. So if it isn't banned could someone please check into this to see why it some how bugs into a different block.
