Hi ElecNinja,
I'm using your mod extensively and find it awesome. But I'm encountering a bug here. From time to time the inserters that put the barrels (both, empty and full) into your auto barreling machines kind of fall asleep. They just don't insert barrels anymore although they could be processed. I have to somehow give them a push by e.g., rotate them +90 -90°. Funny thing though is that all close by inserters with the same job (for other neighboring auto barreling machines) suddenly start working again as well without the necessary kick in the posterior.
I'm not sure if this is related to your mod. But it only occurs with your machines. Inserters at assemblers work like a charm without falling asleep every now and then.
Can you look into it if you are able to reproduce it and maybe even fix it? That would be great!
Cheers!
