So you're the reason I had to write
Exiled.Events.Handlers.Server.WaitingForPlayers += () => { foreach (DoorVariant door in Object.FindObjectsByType<DoorVariant>(FindObjectsSortMode.None)) { if (door.Rooms is null) { Log.Error($"Fixing door: {Door.Get(door)}"); door.Rooms = []; } } };
to fix 106?

I assume you tested this so there's not much for me to review
