As for game testing, I've done this, I've run crafting tests for things like HV Solars, and many other things, tested multiple recipes together, separate, multiple systems, running 1 job, running the same job for hours on end, I've never been able to re-produce it while observing the system.
Trust me on one thing I put an enormous amount of time into trying to solve that bug.
...I could have given you a world where it would stall consistently and reliably, at least once every 15 minutes. Heck, I've had that world saved for over a year. It's an old version, and I get that you aren't planning to fix it, but it isn't a hard bug to reproduce.
