One of the new features to the game is that you can expand certain buildings adding to its value. You can add more classrooms to a school, add additional generators to a power plant, etc.
I'm working on a coal mining specialty and didn't notice that coal shafts can be chained off each other. Well, I accidentally chained a shaft in a spot where I didn't want it and it removed a large building that was previously there.
Coal mining is going well but it is a waste of space how it is currently laid out. I was intending to place any large expansions behind the plant. I wasn't planning to grow out further in the direction it is in right now. Simply turning off the expansion does nothing and attempting to buldoze it selects the whole plant.
It seems like the only option for me is to demolish the entire building and rebuild placing the expansions again. But that's easily over §50k that I don't want to have to spend again.
Is there a way to remove an expansion after it has been placed?
