I found a workaround for my issue. In the planet file Gael A located in ~/GPP/GPP_Planets there is the line: "removeLaunchSites = Desert_Launch_Site, Desert_Airfield, Desert_GroundObjects, Woomerang_GroundObjects" Removing this line and thus retaining these vanilla launch sites has resolved the issue. In my install of the mod other bits and bobs have been removed in my attempts to get things working, but this line being removed ended up making the difference, so whether this fix needs to happen in conjunction with other things (I removed the launch sites - beyond the default one - that comes with the mod) I don't know, and I honestly no longer have the patience to test for that.

Sorry, the full log is here: http://s000.tinyupload.com/?file_id=19844891978818167594 The error happens even when it is entirely still. I also seem to remember that movement does not stop you from saving the game. The log above is from my savegame with other mods present, but the issue happens even if the only mods installed are the planet pack and its dependencies.

Decouple on the launch site, and attempt to recover any of the vessels or save the game. This bug does not only apply to the launch site, but everywhere else in the game as well.
