Generally I'd very much like to avoid making mirror-mode specific workarounds; mainly because there is no way for the script to check if it's running in mirror. Minimum food is the same as the amount to bring per trip, so there shouldn't be any unexpected issues there. It would write it in the logger if it was actually out of anything regardless, and log out.
But yeah, would like to see the video; perhaps you could PM me a gif or something of a few seconds where the script is stuck
