Panel xml has substract rather than subtract

found in default aircraft If this is fixed - will be a breaking change or
will both and work?

Hello. Oops. For now only “substract” will work. We’ll fix that and keep
supporting the wrong spelling of course. Thanks for reporting this. Regards,
Sylvain

There is a similar typo in the mission property definitions. For
“PropertyTrigger” there is a property called “DisableIfIAHasControl”.
