If I'm trying to build a stack of blocks at a lower level next to me, as soon as the placed blocks get to the avatars height, if the avatar is standing halfway on each square, the block you tried to place will not place, but the resource block you used will be removed from your inventory. I can do this with full stacks in a row
I have had the same problem. If you can move away a block or two and it won't happen. But if you are in a tight space, it causes troubles making it difficult to build some types of things.
