NPE: Advance Day stuck

[HomoLiberatorus]

MekHQ 0.47.17
Windows 10
Java 11

When clicking the Advance Day button, the day doesn't advance along the top of the screen.
The Daily Activity Log does show a day advance but only appends the log directly below the previous day.

I have no idea how to reproduce this. It does work as intended after loading a save in my experience, but, when it happens, clicking on "Advance Day" would simply continue to write in the activity log in the same way. (and write more of the same NPEs in the mekhqlog.txt)

Also lots of errors like this:

I'll look into the unit errors.

[sixlettervariables]

That part error means either:

A. There is no campaign object for the part, or
B. There are no campaign options for the campaign

Both of which I did not believe was possible.

I can't seem to reproduce this with the provided campaign. Perhaps a save-reload fixes this very odd corner case.
