Hi,
I noticed a bug with base capture missions. The marker does not update when a new base capture mission is launched. It happens because the old marker is not deleted, causing a conflict with marker name. I assumed that it was an intended behaviour so I made an hotfix who give each marker an unique marker name and change the color of old base marker.
http://nerro.fr/arma/SM4.sqf (I modified lines 21, 30 and 39 and added line 70)
This hotfix will cause a minor display bug for new players if using "exact position" marker parameter, but I did not want to modify more thing.
