Hey Tony!
Okay make sure your levels folder is loading properly. Also, make sure in Folder Config, that level .nw AND level .gmap, file .gmap are under levels.
My word of advice, make a whole new folder called 'overworld' under the levels folder category.. Put it in there with the .gmap file. The green looking level that has all the coordinates... Make sure there is 'level .gmap' 'level .nw' also, put 'file level .nw' 'file .gmap'
In server ops. gmaps=gmapname,gmapname.gmap
Also, go into Graal2001 Levels>Maps> or It might be Graal2001>Maps. Delete the old overworld maps that were on their, and the current ones.
Make sure you have loadmap Mapname.gmap; and loadmap mapname; Convert that to GS2 :P
Also in the tileset script put the same loadmap commands.
Another thing. Ctrl+c to all the things in the Folder Config, then re-set the Folder Config, Shutdown NPC Server, Wait like 5-10 seconds.. Start the server. Put everything back. Then Shutdown Server, reload server
Now, if all this doesn't work. You might want to re-name the gmap and make a new one..
If all this put together doesn't work. Tell me world name and i'll log on and fix it.
