Switching map view breaks with launch configuration (Xbox)

[LightYearsToGo]

Problem: One of my launch configurations (boosters + probe) breaks map view.

No problems until I added an extra fuel tank to my central booster. Now, even sitting on the launch pad, if I switch map views, several symptoms appear. None of my other projects have this problem. The project contains 76 parts in 6 stages. It's smaller than most.

1. The graphics get very weird, e.g. the screen is mostly black and the sun is only an outline.

2. Switching back does nothing.

3. I cannot revert flight (the menu doesn't even come up) and must restart game to clear the problem.

Has anyone else seen this?
