So. I have two mods installed.
TweakScale, and ModuleAnimateEmissive. Something I have noticed is that when I am getting close to a ship (Kerbal or other ship) and I try to use SAS or RCS, the other ship starts to move as well, making docking or getting into a ship while in space impossible. (side note: even when I have a ship face normal/anti-normal and then get to it, it's moved as well. Maybe it just does that if another ship moves at all?) Anyway, I also am running KSP independently of Steam, so I can update when I've saved my games. Any ideas as to what is happening?
