So I was de-orbiting a warped docking assembly with two crewed escape shuttles. I had to re-orbit the two shuttles after the de-orbit burn so i could land them one at the time. 

I had an issue where when I undocked two shuttles, landed the first one and then took control of the second one - it would look like this:

I decided to investigate the bug. So I loaded the load before the undocking and landing and investigated.

I did 3 takes:

1. Undock one vehicle at the time and attempt to move them both by changing between them by using [ (i think - i have a danish keyboard and move them on å) 
2. Undock one, do the re-orbit burn, undock second, do re-orbit burn.
3. Undock one: Quick Save + Quick Load - Re-orbit, undock the other: Quick save + Quick load - re-orbit and check if vehicles were still in one piece.

Results:

1.  The 1st shuttle would fall a part as soon as swapped back to it with "[" hotkay after undocking the 2nd shuttle.
2.  The 1st shuttle would fall a part as soon as I had re-orbited the 2nd shuttle and I used the "[" hotkey to change to it
3.  No shuttle would fall a part - I successfully landed the 1st and recovered then took control of the second via. the tracking station and landed that one.

I recommend turning off vsync. See if that stops it.
