vesselName: the vessel you marked as "docked" VESSEL{<--this is the tag ... } vesselType: 5 for normal spacecrafts, 6 for station, etc... I suggest you to find other occurrencies of the tag "DOCKEDVESSEL" for examples. I hope it helps. Anyway, could please anyone explain what is causing this bug? I'm using ksp with only MechJeb and BobCat's Soviet Pack, it affected all my station's docking ports all at a time... The fix works, but doing it for every single port is annoying.
