I just got curious, having released the campaign editor.
Now, I do not use Minki's logbook, but I tried a career in ETO_01 planeset 3 (Russia early).
The default campaign files are not exactly meant for this, but nevertheless I was able to fly a career, and quit at the end of every mission.
The logbook appeared, and indicated my first kill during mission #3.
The "CAREER00.SVE" was saved in, and loaded from the savedata folder in Planeset 3.




So, there seems to be no problem with the default logbook.
