Thanks again -- this immediately fixed the problem.

thanks! You said "one of the hard dependencies." What other mods do I need to grab?

After installing Interstellar Extended (current version) I'm unable to use two technologies because they have missing prerequisites. Long Term Habitation is sitting on its own below the rest of the tech tree, and requires "short term habitation," which does not exist. Similarly, Logistics is below that, and requires the nonexistent "storage technology." Any clues? using version 1.9.1 of KSP (from Steam), current version of Interstellar Extended, no other mods. Already fully uninstalled and reinstalled everything.
