Hey, I have 1 map divided over 2 servers.
Would it be possible to merge the 2 halves of the map to make it look like it is one?

Can you give more details on how the servers are set up and how the maps are set up?

From your brief description there isn't a way to display to separate worlds on the same map. Using an external webserver you can get 2 worlds on the same website but there is no support for merging maps.
