You can move buildings to an empty slot without swapping since the patch that came out 14 days ago.
And the patch 4 days ago increased ore physics among other things, intended to make the bulldozer/runner issue you're talking about a bit better.
So it seems like you should really download the latest patch hehe! :) The saves carry over automatically. You can also follow the game here or on discord to get a notification when a new patch releases.
Thank you for the feedback and wishlist!
