Docking crashes game to desktop

[Soda Popinski]

The more detail you provide, the easier it is to reproduce and fix the issue.

• What you were trying to do:
  • Dock two craft in Earth orbit at 262km altitude
• What happened instead:
  • Upon clicking "Dock" in the right click menu, but craft vanished, then a second later, the game crashed to desktop with no error message
• What you expected to happen:
  • I expected the craft to dock and become a single craft
• Browser and OS:
  • Chrome and Windows 11 Home version 10.0.26200 Build 26200
  • Intel i7-10700K CPU on a Z490-A Prom (MS-7C75 mobo) 64GB RAM
  • Nvidia 5090 Founders Edition (32 GB VRAM)
• Steps to reproduce
  • Load savegame, and attempt to dock
  • Repeated it from the save game, and it happened again - this time without the docking camera on
    • On second inspection, unlike the first time, the vessels appeared docked for a split second, with the camera shifting, before crash to desktop
• Screenshots or screen recordings showing the issue:
• Error messages
  • No error message, just crash to desktop
• Console errors (if you know how to access browser dev tools)

Additional details:
I edited ...\Kitten Space Agency\Content\Core\PartGameData.xml, adding at line 927:
<PartGameData Id="CoreStructuralA_Prefab_SurfaceAttachMount1WA">
<DockingPort ConnectorId = "_connector31" Force="700"/>
</PartGameData>

When making my craft, I connected Prefab_SurfaceAttachMount1WA to the front of each craft

Here's a copy of the log, but nothing was recorded prior to the crash for about 45 minutes:

I managed to get a successful docking. I think it may be closing speed. I didn't get the crash under about 50 cm/s, but at 1.1m/s, I got the crash.

Checking the original video, closing speed was 14cm/s, so maybe speed isn't the issue.

Attaching another save game, where they're almost in docking range.

A fix for this will be in the next build.
The cause is both vehicles are set to target each other which was not being handled correctly.
