I remember having this problem in the past but not sure what resolved it. I uploaded a new map to the server and synced the fdl. Some clients cannot get the map, it says it is trying to dl the bz2 but after a min it quits and gives them missing map error. I have several other players that got the map with no issue. I have removed the map for server and mapcycle and then the fdl. Restarted the server to see all mention of the map gone. Then reinstalled as before but still same issue for same clients. Is there something I can look at to resolve?
