reproductible crash

I have a 3300 + save, and since cycle 2000 i cant connect the two part of the fully dig asteroid.

if i deconstruct the door or some wall the game crash.

The save is useful to see the issue with the current build at "end game" (nothing more to dig, temperature management is solved by manually opening or closing some hot water radiator circuit. (a cold one is always on to counter the slow rise of temp otherwise.)

I did totally clean the polluted oxygen the only real issue other than the bug is that the game create too much water. i need to remove water, i could block some geyser and clean the water, but the sand is limited so it's not viable.

My save file is linked.
