Nothing is happening as it should be. Some examples:
1. Even though I have tons of coal, the coal generator won't work.
2. The gas pump says there is no gas output line, but there certainly is.
3. The duplicants aren't following at all the priorities, for example, I had everything set at priority 5 except for an area of digging and building, which was set at 9. I had enough material for everything, and they were able to access the area, and yet several days went by without them doing any work on the area. In fact, I'm not even sure what they were doing.
I have had a few other save files that didn't seem to have these issues. These are just a few examples, but it just seems like nothing is working as it should be.
I was just paying the game normally, It isnèt a specific bug or crash that happened.
