Thanks for a good balanced mod.
There's a small issue: when repairing engine / taking parts, it won't take a wrench from the bag, only from main inventory. Usually I do the repairing jobs while having all required tools in a toolbox.

works really well + great balancing.
underrated as hell

Yes you can add this to an already existing save

can this be added to an already started save?

Thank you! Gonna test this

Thank you for this, we were just balking at how hard it was to get meaningful engine repair progress vs. parts spent last night!
