Through days of testing leading up to the Make Arma Not War 2025 submission deadline and then becoming my conclusion when I found the sample missions Patrolling Group and Waypoints sample data that the AI does not move beyond the default waypoint such as AIWaypoint_defend.et. That was my experience in those sample missions as well as in my own modless development - the AI would not move to the SlotWaypoints no matter what.
Game Master could give AI waypoints and AI would act on Game Master issued Waypoints.
Not to be a crybaby, but this halted my plans for an entry into the contest - if it were patched and a new deadline to the Make Arma Not War contest, I would submit an entry.
