I found that sometimes the bumblelyzer may get stuck when scanning multiple bumblebees at the same time, consuming bumblebees, paper and honey but not outputting. This seems to be related to the parallel mode of the bumbleyzer. At this time, if another bumblebee is put in, it will operate normally and output bumblebees that have not been outputted before.
I do the HV bumblelyzer. I don’t know if it matters.
