I was creating a map, trying to place NPC's on map - (doesn't seem to work), Map Editor hard crash, rebooted PC!
Load Map in Editor and try placing NPC's on Islands.
Files - Debug.err + 4Coners Map files.

Update:
The NPC's didn't show up when I first placed them on the map but, when I restarted the Map Editor, the NPC's are now showing up. Test create random map, then try to place NCP's on the new map, the problem they don't show up, until you save the map and then reload it. The crash problem above may have been caused by trying to place NPC's again and again because they didn't show up on the map the first time.
