I started a new save to enjoy the 2.0 and space age dlc, and am playing with my brother and enjoying my time very much and playing until the wee hours of the night as Factorio is known to be more addicting that's crack.
Anyways I was making a train network, and tried to add an interrupt that if target destination is full, go to waiting station Until {Wildcard Demand} is not full. However this doesn't seem to work and I see no resources online explaining it. Help is appreciated
