Custom hitbox sizes for blocks don't rotate when the block does.
I can provide more information, including screenshots, if necessary :)
Steps to reproduce (with workspace):
Place block Gargantua Stem on top of a block. Then place it on the side of a block.
The hitbox on the side of the block is exactly the same as the one when placed on top of the block, when it should have rotated.
There is also another block rotation issue in this workspace, but I will open a different ticket for that.
Could you provide example workspace as generally, they should be rotating?
