Every single piece of my base (even the roof pieces) are supporting every other piece.
My base has 4 ‘stilts’ holding it up- each is a scaffold touching the ground, surrounded by stem walls.
If I recycle any single piece (even the roof pieces at the every top), the whole base collapses.
I’ve tried reloading a save, and restarting the game.
EDIT: I’ve just replaced one of my stem walls with a pine wall, and the whole thing is fixed. Although, now it says everything is supporting 0 pieces, which also isn’t correct.
