1. Create a blank mission, place a player.
2. Create initPlayerLocal.sqf with the following code inside:

waitUntil {!isNull (findDisplay 12)};
(findDisplay 12 displayCtrl 51) ctrlAddEventhandler ["Draw",
{

params ["_map"];
systemChat format ["scale: %1", ctrlMapScale _map];

}];

3. Observe behavior on local machine (map returns to players position after closing and reopening)
4. Export the mission to MP and observe behevior on dedicated server.
