I do a mix of both. I have some standardized setups that I use for thing like kitchen/ butcher/ freezer that I plan out pretty quickly, and then I adapt based on the terrain and my needs.
I canât sleep until I know where everyone room is going to go.
Same, omg. I can't unpause until I'm done. In my current save, I left a bit of empty space because I've never planned for a specific mod's content and I'm not sure how much room it will need, and it's driving me crazy.
