Speculating: what may have happened is that you had an invalid path in
your scenery or aircraft directory list, and also had disabled the
"save-on-exit" property only at the end of the command-line. fgfs first
reads "preferences.xml", which enables "save-on-exit" by default. Then
it starts evaluating the command-line parameters one by one. Finding the
invalid scenery or aircraft path, it was exiting immediately (due to an
error, which has been fixed already), and never got to evaluate the rest
of the command-line, so "save-on-exit" remained enabled. May not have
happened if --disable-save-on-exit first was first in the command-line...
