[1.7] Stack separator making ship disappear?

[Shmauck]

Me again with another strange thing happening. I have to carry four large fuel tank modules to my space station in LKO. For the first two tanks I used a one-way launcher which would deorbit and rapidly deconstruct. I used to dock my small construction tug to dock to the payload, undock the payload from the launcher and bring it to the station to dock it there. All fine. 

Now I modified the launcher so that it can survive reentry and I used a stack separator to connect the launcher and the payload. End result is that I can't use my construction tug anymore after separating the launcher and the payload. This happens regardless of the sequence I do:

• I dock the construction tug to the payload and then activate the decoupler
• I active the decoupler first and then dock the construction tug to the payload

Both ways I end up with the launcher still being a ship, a debris part which is the stack separator and nothing else. The construction tug and the payload completely disappear. Why is that happening? Any other ways to do it?

Disappear like...really gone?

Do you use any Heavy or Root Autostruts?When docking/undocking with crafts that have heavy autostruts it might cause the kraken to attack.(If there are heavier parts, long distance roots etc).

If thats the case try to change them to grandparent or disabling them after they get in orbit.Maybe it will help.I had this happened before, after i reloaded the vessel a big part of it was just missing.

(Silent Kraken attack  .) !!Also make sure you do a save before trying switching autostruts in existing vessels.It might not go well!!

Ummm no, sorry for being misleading and unspecific here.

The docked tug and payload are visible on screen, they float peacefull in space right before my eyes. But switching to that craft with bracket keys is not possible anymore. 

And that is weird, especially in the second case when I activate the stack separator first, before I dock the tug to the free-floating tank. I am in control of the tug, then it docks and I lose control. 

Seems like the tank is considered as the parent and the tug as the child and since the tank has no probecore and no cockpit, I lose all control. But it is also not considered as debris of the launcher. It also dors not appear in the tracking station. Confusing...

And no, no autostruts involved so far. 

I am not at my computer right now but the last hope I have is that I can select the crew hatch on the cockpit and EVA and reenter the pilot to regain control. If that doesn‘t work I can still relaunch the whole thing without the separator and try again.

Huh thats a weird problem  .Do you have Max Persistent Debris on General Settings set to 0?If you have it to 0 it will remove them immediatelly...kinda...if you switch to tracking station.

Try also changing the Seperators Force Percent to zero.Have you shift moved parts or clipped anything?Other than that trial and error, you may actually have a bug or something.Good luck!Maybe someone else can give more help!

After some additional testing I must say that I am just stupid. 

In fact, the separator DID NOT separate the payload from the launcher which is why no craft appeared in the tracking station and I was unable to switch to it using the bracket keys. Sorry to bother you but thank you for your help.
