Btw, can confirm the b599 version was causing this cause when I switched to b598 this issue went away. Not sure if this still matters with the 4.2 update being released today.

And also if it is possible, can provide me with the .log file as well, thanks.

Sure, here's the logs I had at the time: https://gist.github.com/skellitor301/1e02a4f1109c426276d696a2d7c1ba12

I came across a bug in the experimental version of CoI (Update 4 | V0.8.5 (b599)) that causes sorters to eat resources going into them when full. I'm not entirely sure if this is a bug between experimental and this mod but I don't really have another mod that affects belts. I've uploaded a gif showing this bug here: https://i.imgur.com/MZBdMKl.gif
