(Note that this is a very simple XML patch, and as such should work through updates unless either Rimworld or SOS2 undergo some major internal changes.)
This mod reduces the cost of Save Our Ship 2's basic structural buildings to save you some time crafting components.
Some of the changes made in this mod were added to the base version of Save our Ship in the 1.5 version and beyond, and so this mod is no longer needed unless you are playing in an older version (in which case it still works just fine).
If you're still reeling from component costs, I suggest the mod 'Reasonable Components'.
