Currently, roof tiles change shape based on what is next to them.
This is very intuitive while building, proven to work and I think it should stay that way.
But this dynamic change also occurs when breaking what is next to them.
This is the core principle most ‘bunker’ base designs are based upon. If breaking the twig does not change the state of the roof tile, there is no way out of the base.
My suggestion is to remove the latter behavior from rust. Or if this inhibits building too much, make the behavior only last as long as the block can be demolished with a building hammer.
I consider bunker bases unintended behavior. If you do not; just downvote this suggestion. If I have overlooked something, like other intended behavior that would break because of this proposal; leave a a comment.
