Hello. Sorry if this is the wrong place, but I'm trying to forge on Sandbox, But I'm experiencing a problem. I've put the starting points on the skybubble and deleted them from the bottom, and even put a few spawn points at the time, but when I try forging on it, I always spawn on the ground and not in the bubble for some reason. I don't understand why.
Your problem may lie in the Gamemode you are currently playing. In Forge, you can spawn anywhere there are starting points. However, once you play the gametype you placed the spawn points for in the Custom Games lobby, you should spawn in the right place. Hope it helps, ~The Cheat~
