soooo is it safe to assume that as of 0.95.1a this mod has been abandoned and therefore will never be compatible with 0.96 and on?
Pretty much, yeah; Sutopia is most likely
not planning on returning to the Starsector modding scene, and
all mods that rely on the Concord mod library (which was
already unstable with v0.95.1a) won't work with v0.96...
...unless you can find old-enough version(s) of Sutopia's mods that pre-date Concord; case-in-point, an older build of Modern Carriers, since it has some features that I am unwilling to part with; but as for
this mod?
Neither version release(s) available on Github pre-date the Concord requirement, so yeah; Fair S Mods is VERY much dead and buried, barring Sutopia returning to mod Starsector again, which is not at all likely.
