I found a typo in simuconf.tab
# remove password of abandoned companies (wihtout any building activity) after x month (0=off default)
unprotect_abondoned_player_months = 0
Shouldn't it be "abandoned" instead of "abondoned" (just like in the help text one line above the setting)?
Unfortunately, "abondoned" is what the game looks for. Fixing the typo will either be a breaking change, or require some compatibility hack for a long time to come. (The HTTP standard has actually operated with a typo that apparently can't fix for a decade or so.)
We could certainly allow both.
