Create a empty map called login and make all classes spawn in this map, create a switch called "first login" and make a autorun event in this map, then if the "first login" is false then teleport player to (where u want players start), if true then teleport player to graveyard, after this go to map where u want players start and make a autorun event (if first login is false then set first login to true)
so when players login at first time they go to start map, when they die they go to graveyard
