I started a game using a zig-zag pattern across the available space. For each “long” section, I started with chassis, body, paint, etc. One in each. As I research, any particular part of the process can be rebuilt without having to move the others. You get the idea.
As I finished the build out of Body section, the game is complaining about something in “Fit Electronics” Either the error is mislabeled, or you have a dependency you shouldn’t have. Looking at the build list, I can’t determine what is missing, if anything.
I have a zip file with my saves and the debug folder.
