Unable to Undock

[Xurkitree]

In my current Grand Tour, I have a Ion Tug Probe docked to my mothership. However, I can't seem to undock it - Whenever I try, nothing happens, except the Undock option disapperears.

Any help? I cannot continue until this is resolved, so speedy help is appreciated.

Here is a picture of the ship -

The big stack of 0.625m Xenon tanks with a docking port is my Ion tug. It is connected to the mother ship with a Jr.Docking port. It has an OKTO2 Probe core on it.

Timewarp doesn't help, neither does quickloading or restarting the game.

Maybe your ship/savegame is corrupted. Have you already checked your log or kept the console open when you tried to undock?

There used to be a stock bug that made docking ports sometimes get stuck into a state where they 'thought' they were undocked, but were still attached - which resulted in the problem you're describing, that they could not be released anymore. I think it was never definitively fixed and it reappeared a few times in newer versions. A bug fix mod used to solve the issue, but that mod hasn't been updated for a very loing time and won't work with newer KSP versions.

The solution unfortunately is not something you can do in-game: you have to edit the save file to fix it. It can be done in a text editor, but it's probably easier / less error prone to use this:

Make backups of your savefile before editing etc etc.

What do I have to edit within the savefile?

I haven't used it, but from the description: it's supposed to show a list of parts for the craft in your save (among other things), and you can rightclick the docking port for the tug and 'repair'. The last page of that thread has someone asking about fixing a docking port, and the author explaining - you might want to read that exchange.
