I can't move/rotate active vessels in orbit. When warping, the vessel does not move in it's orbit. The server log doesn't show anything interesting, but here's my KSP.log:

I get lots of NREs towards the end when packing the vessel for orbit.
This is possibly not a DMP bug, because I get the same behaviour with the DMP save in single player, but I'm submitting it here anyway because it didn't appear a couple of days ago (with exactly the same KSP setup).

Never saw this again, probably a mod issue.
