Okay, so when I built my map, the spawn points worked perfectly in Forge. However, when I tried the map in a custom game, I die the moment that I spawn. Can someone help please?
If you have a safe zone on the map not selecting a certain spawn point or a kill zone over the spawn point you will die when you spawn.
Try delete all on the safe zones. If you accidentally placed one it would cause this. Take a screenshot since knowing where the spawn point is might help.
It's a safe zone. pyro6666 is right, I recently had this problem with an infection map and it turned out while I had been forging away and letting my friends kill each other on the map, somehow a safe zone had been placed. Once I deleted it, the problem was solved.
all the map has to be in a safe zone if you placed one. if theres a respawn point out of that safe zone, you'll die instantly
