Parts floating off attachment points (Realism Overhaul)

[MagiMaster]

I installed Realism Overhaul from CKAN and when I tried to launch a ship, this happened (skip to 0:47 for the main bug):

This is from RO with all suggested and recommended mods. I'm pretty sure the only thing I changed afterwards was to run DDS4KSP. I haven't been able to narrow it down to one specific mod, nor have I been able to find anyone else reporting this problem (though that's probably because I don't know what to search for). The same thing happens after removing several mods and/or parts, but doesn't seem to happen in an unmodded game.

The video also shows two other minor problems. In the first part, I was right clicking on parts in the VAB when it suddenly stopped popping up the tweakables menu. I have narrowed this down to TweakScale.

Finally, I'm reasonably sure the VASIMR engines aren't supposed to stay on like that before they're activated, but it seems to be purely cosmetic.

Does anyone have any suggestions on what might be causing this or how to fix it?

[MagiMaster]

For anyone else having this problem, it seems to be caused by either Procedural Parts or RealFuels, or some interaction between them.
