I'm having an issue where, on load after a save, the cargo platforms are spinning off in some random direction with super-speeds as opposed to being in my cargo bay. If I don't pause and delete them fast enough orbiter will crash.
It may be an issue with XR-5, since there also appears to be a ghost XRPayload_Bay spawned in the sun's orbit (ie far far away from LEO where I am). I don't know.
