src/cheat.cpp:188–286

The "override_existing" parameter is used only in cheat dialog import. Since the default behaviour will reset numsubcheats to 0 everytime, In game loading, this is absolutely right, but when importing in cheat window, resetting numsubcheats to 0 will override existed cheat items to make them invalid. */
