Due to the crouch button being inseparable from the fly down button on the controller, you have to fly down and try to place blocks on top of blocks that have inventories, while doing this it is possible for a ghost block to be placed, you can stand on it but if you try interact with it the block will disappear… I have only noticed this when placing a block that has an inventory next to another block that has an inventory.. i.e placing a hopper so it connects to a chest, or vise versa, or the same with droppers and hoppers, or chests droppers. It’s not easy to replicate since it doesn’t do it every time. If we could have the ability to reassign the crouch button and separate it from the fly down button on the controller then this would help a lot.
