Issue description: I'm using the builder to move a mansion on my island ( playing on a modpack ragnamod 5, this is a skyblock) but there is only around 40% of the blocks that are moved on my island and the rest is still in the space chamber, I don't know what to do
Steps to reproduce: create space chamber around the mansion then right click with the card, put it in the builder, put a lever on the builder and turn it on

Realize this but is a bit old, but it's still open so.... Some additional info that might relate to this. I ran into an issue that looked like this in the MC 1.16.2 version, and I was able to work around it by fully powering the builder. It seems like the builder just skips blocks it doesn't have power to complete the transfer.
