Game hardlocks upon gameover/reload

[Internet Waste]

As it says on the tin.

I've encountered this multiple times: With the patient puzzle in the rooms 30X, with the plants, with the nurse pantry puzzle, and now more recently in the 3F in what I assume is the ending, the red tube/giant puzzle nurse.

Whenever I am halfway through a puzzle, if for some reason I get a gameover or stop playing and come back later to my save, the puzzles are locked: Materials I've put down in their place are disappeared, doors opened from puzzles are closed again, and now more recently and egregiously, after I've done all rooms except the last one to finish removing all the fluid from the tank with the giant nurse that has the last red tube, upon reloading, all of the switches are flipped ON (and impossible to interact with them), but the tank is back up to full.


It's getting very, very, VERY old having to restart the game from scratch all the time.
