ArmA 3 can break anytime. Do not worry. I have foreseen it. Debug console available for first player, host or admin. You don't need to know script commands. Just enter the simple commands that are written in the briefing all mission.
Example 1: All conditions are met but the mission does not end. Enter the command in the console end=true
Example 2: You need to regroup the squad on yourself. Enter the command in the console regroup=true
DO NOT USE THIS COMMANDS WITHOUT A REASON. You will break the mission script. Exception for command "regroup=true" Scripts do not depend on this command. You can use it anytime you like.

Um, no. Do not use this command in a helicopter. Your team won't appreciate a joke like this.
