To be clear I know this is entirely my fault. I just expected the invalid blueprint to throw an error message, not crash the game. Details on how to reproduce: So I was making railways blueprints, and decided to use the snap to grid feature. To my annoyance, you cannot snap to a rail's midpoint, whi...

if you feed more than one full belt of any item, it will back up and get stuck. This is because on the way back, that item is filtered and must pass through the yellow splitter. So you can use full belts instead of half belts, but that's a limitation. But! if you want 1/3 of one item, 2/3 of another...

Even more! https://i.imgur.com/PxgR07V.png 0eNq1WO1uozAQfBf/hgqDP4BXOVUVIU5iHRhkzLVRlHcvNLoUJTjdhfQXAsHMMuNd7/pENlWvWquNI/mJ6LIxHcn/nEin96aoxmfu2CqSE+1UTQJiinq8Ux+tVV0XOluYrm2sCzeqcuQcEG226oPk9ByAQbq20s4pO/k8Pr8GRBmnnVaXgL5ujm+mrzfDmzm9otyEEJC26YbPGjPyjpGIFx6QI8lDmkYvfODYaqvKyxtsDPMGOoZDywfQYgY6gUOn...

but what if more compact? https://i.imgur.com/T5kjFbX.png 0eNq1WWtvmzAU/S/+TCr85PFXpqmi1E2tEUDGbI2q/PfhRutQa2f32uunJATOuT734QO8kodh1bM1oyPtKzH9NC6k/fZKFnMcu8Efc+dZk5YYp0+kIGN38r/0y2z1shyc7cZlnqw7POjBkUtBzPioX0hLLwUYZJkH45y2u8vZ5XtB9OiMM/oa0NuP8/24nh62M1v6jvIhhILM07JdNo2ed4M6cH4nC3LevtGG3cmN5NFY3V9PE...

So... I may have come up with two more designs. I am really happy with how compact they are 4 Items Sushi Belt https://i.imgur.com/2dek68Y.png 0eNq1mE2P2yAQhv9KxNlZBQz+OvbWc4/VauV4SYJqYwtw1SjKfy9eq5GVJe4M0Z4iE3ifl2FmQnwh+3aUg1HakepCVNNrS6qfF2LVUdftNObOgyQVUU52JCG67qanQ23d1pla26E3bruXrSPXhCj9Lv+Qil4T...

Here's my design inspired by this thread. It takes advantage of red belts being twice as fast as yellow belts. Downside: required red belts, and cannot be done with blue belts https://i.imgur.com/9wIsgPs.png 0eNq1WMuOmzAU/RXkdTLCxjySZRf9gVm2o4ghJmMJbGSbUUdR/r0G0pCkJvGjXUUQc8651/dlH8F705NOUKbA9gj2RFa...

Oh I can see the challenge. But for practical purposes this is working fine now. I did change one thing, now my requester station will only be enabled if any of the items drop below half the requested amount. Before this my train was doing a whole round trip for one magazine of ammo. Not ideal

I'm not sure why you would need many combinators? The way this works is: take the items we currently have over the green circuit, multiple all by -1 to get the negative, and feed that to the red circuit. Also on the red is the output from the constant combinators. So if I have a request for 200 ammo...

So I came up with this design recently, and I think it's neat so I figured I'd share it here. There are probably many designs like it, but this one is mine :D https://i.imgur.com/MLByQRT.png What this is: a pair of configurable station that can keep an outpost supplied with any items that may be req...
