It used to be possible to tell the planner that multiple belts were available to use (yellow, red, etc.) and it would automatically select which belts to use based on how much ore the miners were outputting on a single line, so for the first handful of miners it would use yellow, and once yellow was filled up it would then use red, etc.). Now it appears to only use the highest tier it knows about for the entire line.
I do have some other mods installed currently like RSO that change ore (it’s infinite like oil on the map I’m playing now) so it’s possible that’s the issue.
Anyways I love this mod and use it all the time and am very thankful you’re maintaining it for 1.1
