Construction Setting a radially attached docking port as the assembly anchor breaks the assembly when leaving and reentering the VAB [Craft into the ground/floor]

What I expected: my craft to stay as I left it when I left the VAB

What actually happened: the docking port and the part it was attached to stayed in place, along with all radially attached parts, but any parts attached by snap points were moved under the floor of the VAB and disconnected from each other. Additionally, the part which the docking port was directly attached to had its top snap point removed.

Steps to replicate

1. place a few tank parts assembled together either vertically by their snapping points or radially

2. radially attach a docking port of any size to one of the tanks

3. using the assembly anchor tool, set the docking port as the assembly anchor

4. leave the VAB to KSC or any other facility

5. enter the VAB

@TRAILtheGREAT, good finding! I was able to reproduce it with the steps so it's great.

I made a rocket, launched it, reverted to VAB while it was in flight, and the craft loaded with everything deleted but the assembly anchor and the part the anchor was attached to. None of the nodes are available to attach more parts too, but loading the craft again doesn't do anything. Launching the craft also just loads the two aforementioned parts. The save file still has the image of the full rocket.

What's interesting is the autosaved workspace shows the full rocket

@boeing186, merged your bug report with this one.  Your craft is stuck in the ground (thus, not the one I sent you in DMs). I doubt it's due to a docking port and that's interesting. The craft you sent is already in the ground so can't check but that will help with other report about this.
