Gearshifts won't affect them, their starter won't appear in the menu, etc.

Fixed in V20.0.0.

That make sense given how I coded the indexing. Will fix. do you have a test build?

V20 Beta 30.

Er, no. Meant a pack that has such a setup that would cause such a bug to become apparent.

IVV "V1.5" I guess, although the only difference between V1.4 (released) and that is the above JSON. Texture is irrelevant for it, but it's supposed to take a variety of parts including engines. (I'll make it more expensive soon)
