I am getting a bug that I am able to consistently reproduce.
I cant recover my vessel, save my game or return to KSC once landed at Rhode after a mission.
Another user seems to have had a very similar issue to me and got a solution in this thread. He was using Galieo's planet pack but I think this is a common issue between mods that replace planets and launchpads.
Here are my installed mods and the debug log when I click "Recover vessel when landed"
