Hi, first thanks for the mod!
I am unsure if this is a mod conflict but I am running Krastorio 2 and Space Exploration if that helps.
The save will crash upon removal of tiles underneath an furnace or assembler. The game itself does not close I just get thrown to the main menu.
it does not crash when the entity on top is removed first then the tiles.
Here is the notice:
Notice
The mod Stable Foundations (1.1,4) caused a non-recoverable error.

Hope this is helpful!
