Awesome, I hope it works well!

This is something I use:

var storage = Game.spawns.playerName.room.storage;
if (creep.pos.isNearTo(storage)) {
creep.transferEnergy(storage);
} else {
creep.moveTo(storage);
}


I've got the same problem, can't create spawn and no errors shown.

If I look at the network flow of Firefox, I get a 200 response code but with an error message "Not allowed".
