Reproduction steps:

Load the linked save game,
Right click the rocket's docking port facing the mining base,
Select undock,
--> Fails
Right click the docking port to which it is attached (K&K),
Change to primary docking node,
Select undock,
--> Crash

You can undock the other ports towards the end of the vehicle, but ultimately you cannot undock the rocket from the K&K docking port?

Save Game:

The problem seems to be caused by physics settling at warp transitions that have caused the nodes attaching the docking port to the rocket to become physically separated.

It seems to be Mobile Drill Base PART #49 and PART #58 specifically where the problem occurs:

I'd tried spacing them out but all that did was make a visual mess:

So I changed the temperature of the gangway (part #58) to 5500, which was enough to destroy it and separate the vessels finally.

I have the same problem, most of my mods are visual mods, but my two module base was miss align and I can't undock to realign, I tried removing Autostruts and the craft is floating separately but the game loads as one, I destroyed one of the modules docking port once but the game still loads as one, refusing to separate the craft. Please help
