Construction Assembly corruption in VAB when multiple attachment points are valid

[Lyneira]

When attempting to merge a rover with a lander in the VAB and hovering the rover near the lander's docking port, the rover flicks rapidly between different possible attachment options. It is then very likely for the part orientations on the rover to get jumbled up like this:

To replicate:

• Download this craft file bundle and unpack in your save's Workspaces directory.
• Load workspace "Rover Lander"
• Merge "Mini Rover 0.1" with the Rover Lander, review the shape.
• Note that the rover is now the main assembly and the workspace title "Rover Lander" has been overwritten with the merged workspace's title. (shouldn't the lander remain the main vessel when merging? And keep its original workspace name?)
• Make the lander the main vessel again.
• Grab the rover by the central battery and move it around the bottom of the lander a bit.
• Note how the rover flicks rapidly between different possible attachment options, which would make it difficult to attach the two docking ports together.
• Rover parts should become noticably jumbled as in above screenshot very quickly.

Workaround: Cover every undesired attachment node with a nosecone. This might be a tad impractical.

• KSP Version: 0.1.2.0.22258
• Operating System and version  (Windows 10, Windows 11): Windows 10
• CPU and GPU: Ryzen 7 3700X, GeForce RTX 2080 Super 
• Mods: none.

Yup, I see this regularly. In my case it's most often the small RTGs or any docking ports.

See this a lot

Yes, this is very frustrating, spending much time designing a cool rover vehicle and then trying to carefully attach it where you want it and, whoops, in less than 1/2 second your cool vehicle looks like something better sent to a junk yard.
