Principia does not run in debug KSP

This issue has been tracked since 2022-09-04.

I suspect the issue was introduced in #3303. #3201 is also suspect.

What I believe to the cause (apologies for screenshot-of-code):

For the uninformed: what is "debug KSP" and where do I buy one?

It is running KSP's unity in debug mode. cf.

I think it needs lazy initialization of psychohistory_mesh_, prediction_mesh_, target_psychohistory_mesh_, and target_prediction_mesh_ in class Plotter.

Essentially yes. You're instantiating Unity objects during the Plotter constructor [static declarations at the class level], which is not allowed. The exception is swallowed or suppressed in non-debug mode. More appropriate would be to put those initializations into a new Plotter.Awake() method, which gets automatically called right after the constructor.
