Had an inconsistent crash when trying out the dehydrator. First batch of food (mushroom wrap) caused a crash. Next time i tried with surf and turf it worked fine. Then mushroom wraps worked too but it crashed with pepper bread.
It might possibly be caused by dupes delivering partial portions of the food. For the first run they delivered 5 different mushroom wraps warying in weight possibly with different spoilage progress and some spiced and some not.
It crashed at the moment it finished it automated part.
Build a dehydrator and supply it with multiple small portions of food.
Make sure portions vary in spoilage.
Add spices to some of the portions but not all.
Game should crash when the machine finishes the automated part (before the dupe comes to empty it).
