Don't know if this is intentional but my level 1 interior advanced martial plot consumes A TON of lead daily. More than a level 3 interior machine parts plot with a level 8 worker produces in a day. (unless the plot needs to be refreshed each level up to generate the correct amount, idk)
Also I believe you said commercial plots were pushed closer to the endgame (kind of), completely missed that but now that I'm constantly out of cork, I can see that.
Edit: never figured out if interior plots not changing their appearance until refreshing is a feature or not. But at least they change their functionality correctly when they're levelled, right? On this note, I'd love it if there was an option to make a plot appear as level 2 when it's level 3. Like, the level 1-2 armor shop fits much better with the minutemen theme.
Edit 2: still consumes like 19 lead and produces 9. Worker is level 9 now, plot is refreshed. Both are interior so should be fair even if the martial plot is an oversized vault door (working on a little pet project called "vault 3 for Gremlin" inside the Udderworld)
