As title says how do i remove player name from map marker after the attack the base. 

by disabling it =p

Show Owners Name on Map Marker

I cant seem to find anything in the config or data files and folders for that, well atleast in the free version.

},
"Map Markers": {
"Marker Name": "Raidable Base Event",
"Radius": 0.25,
"Use Vending Map Marker": true,
"Use Explosion Map Marker": false,
"Create Markers For Maintained Events": true,
"Create Markers For Scheduled Events": true,
"Create Markers For Manual Events": true
},

you can't remove it in the free version. it's not an option yet.

            public string Mode()
            {
                if (owner.IsValid())
                {
                    return string.Format("{0} {1}", owner.displayName, DifficultyMode.SentenceCase());
                }

                return DifficultyMode.SentenceCase();
            }​

            public string Mode()
            {
                return DifficultyMode.SentenceCase();
            }​

thank you
