I'm also having trouble with the station crew rotation missions. I successfully did a rotation in Kerbin orbit but cannot complete a rotation for the stations in either Mun or Minimus orbit. Same issue that has been described before with the dock objective becoming unchecked as soon as I undock. I am running the latest CC and 1.3.1 of this mod. Edit: I have both the Mun and MiniMus station rotation missions active at the same time. Could that be doing it?
