I have 1.3 up and running. This is the first server i have hosted so my experience is limited. Everything has gone smoothly, except I spawn in the same place no matter which island i choose. It seems like each time the server is restarted it picks and island and will only spawn players on that island. If i restart the server again it will pick a different island. Is anyone able to tell me how I can fix this? I took a look at it in grid editor but I am not sure what i am looking for.
