I'm very new at this mod and I am making an andesite alloy farm, but it's generating more gravel than it makes flint. The flint and gravel reach a basin from two different conveyors, but when the basin fills with 64 gravels and another gravel reaches it, flint can't enter it anymore and the production stops. How can I deal with this overflow on the belt? Is it possible to re-route the extra gravel to where flint is made so that it doesn't go to waste and make the gravel/flint ratio more equal?
