Structural failure following time warp exit or switching vessels

[THX1138]

I have a some stuff on the Mun which has been fine for a long time but now I'm finding that when I exit timewarp or switch vessels, some of the vehicles buck like a bronco and this sometimes causes structural failure of one particularly vulnerable vehicle (an engine clips into a wheel very slightly). I uninstalled all my mods to check whether they were the cause and the problem remains. Here's a video demonstration:

It can be resolved by releasing the claw from the end vessel with the mining drills and then reattaching.
