[MOVED TO SPACED OUT - BUG TRACKER]
So, this has happen to me every single time I load into my save. Every time I load the game the compost buildings that I have are shown like they don't have anything, like they are not being used, they are empty, but they are not. After the first flipping is required after loading the game, it goes back to normal.
In the attached image you can see that there is polluted dirt in the compost but the graphics seem like there isn't.
