Go into editor and execute the following line in the debug dialog:
with uiNamespace do { RscDisplayGameOptions_showDifficultyGroup = compileFinal "diag_log text 'owned!!!';"; };
Now click into the Configure->Game options menu. Menu is corrupted and RPT will have line "owned!!!" in it.
Exit single player editor, join a multiplayer server and repeat the above menu step. RPT will show owned message there too.
RscDisplayGameOptions_showDifficultyGroup is initially defined in \a3\ui_f\scripts\GUI\RscDisplayGameOptions.sqf
