Saving Markers
You can save markers by setting the saveMarkers attribute in CfgGradPersistence to 1,2 or 3.
1: only save editor placed markers 2: save all markers 3: save only markers created during the mission
User created markers will lose their owner. This means hovering over a marker will no longer show its owner. However users will be able to delete those markers.
Because markers lose their owner, it's impossible to assign loaded markers to the correct channels (i.e. side channel might be side-channel WEST or side-channel EAST, ...). This means that only global-channel markers will be saved.
Polylines (user drawn lines) will not be saved, as there is no script support in Arma yet.
