Innsewerants indicated in the 4.0 blog post that he had a lot going on in his life, and his last online activity was June 5th. Unfortunately, he might have needed to give up on KSP and this mod for more important matters, which sucks because to my knowledge he was the only one working on mapping. Seeing as the mod is so popular and people are scrambling over getting the dated builds to work, it would be amazing if he showed up and either updated the community on the mod progress or formally handed the project off to someone(or anyone who wanted). Either way, its a great mod and it would be a shame to let all of his awesome work go to waste because he was unable to continue development and new Squad updates caused problems in the working builds.
