Issue description
I'm watching my inputs and outputs on my exhaust scrubber and the input for the exhaust randomly stops loading products into the scrubber. Outputs are empty. Water and limestone are loaded. I can watch the operations window and it just stops. It says waiting for products. Pipeline is full of exhaust. Connections are unchanged. Literally working then just stops loading exhaust.
I've tried reloading the save to earlier saves and it keeps happening. Game is updated. Verified integrity of the files. No fix. Game breaking.
Reproduction steps
I'll be minding my own business. All operations are normal. Exhaust scrubber stops loading products from exhaust pipeline. Just open the exhaust scrubber operations window and wait. Pipeline then backs up. Exhaust doesn't load. Water and Limestone operate normally.
