I have been trying to just look at my map and see the player spawns I created. When I build the mod it tells me everything is ok. I compile the map with everything you are suppose to have on, and I've been ending up spawning on top of my box room I created. The light i made as well was not there, but when I go in and look at the map it says everything has been placed. Can someone please help me with this thank you ^_^

in radiant make sure both your multiplayer spawns (the 4 small script_structs) and single player spawn (the bigger info start box) as well as your light are in your room. Then recompile your map and build your mod again then you should be good to go.

my guess is that your single player spawn is above your room

Make sure light isn't in the floor sometimes it will spawn there... Hope this will  you
