Thank you very much for playing and for the feedback, it was very important to me! I'm making changes for improve the mod , and end these problems that you reported.
About the direct miner->smelt stall
I tried to make the exit of the furnaces with more exit options (4 instead of 2), but it did not work. I've tried also to make more places for entrance, but furnaces can only enter 1 ore at a time ... I'll keep trying something to solve this, but I think for now we will have to withdraw with inserters when we have more than one ore entering the furnace.
Because of the variety of ore in the same place, maybe we have to build some chest for "buffer" that we use less.... otherwise it will really start to stuck the whole line of ores...
If you have the code of BP for recirculate scrap plate, please copy here for us!! XD Thanks!
Soon you will be able to use chemical machines to recycle all machines. Sooner you unlock this tech, better. The "scrap"is the final thing that generates after all recycling process. Now you can turn this in mines, grenades, landfill, big chests and solid-fuel. If you have any suggestions for what to do with it besides these things, it will be very welcome!
I really happy you are enjoying (or suffering XD) this mod. Thanks again for the feedback
