Loading existing save with preview build causes food in at least one fridge to mysteriously disappear.
Load up the attached save file using the current release build, and check the fridge in the starship Sojourner. There should be 9kg of Berry Sludge in there. Catalina calls her friends, excited about her mining mission.
Now switch to the new preview build U43-522820-S and load the same save file, and check the fridge again. Alas, no fruitcake. Catalina is sad. Her stomach will rumble all the way home -- assuming she does not starve to death first!
The fridge on the frozen forest planetoid may also be affected.
