I made a Grifball Stadium on Sandbox (In the Crypt) and when ever the game starts you spawn inside the Crypt, but when you die you Spawn outside. I deleted everything outside the Crypt and I set up the spawn points correctly. What's the problem...
Make sure your not putting the spawn points down while in the all gametype setting. Go to assault and do it. Make sure you have starting spawns and spawns. Make sure one is defenders one is attackers. If you have done all that I don't know what else I can help you with,
file share the map and i can have a look at it for you i am about to start to build the official Crypt Grifball court and i don't want to run into the same problem, so i would be glad to help
