Description Andrew Fuerste-Henry 2021-07-19 20:38:56 UTC
To recreate:
- find a bib with just 1 item on it
- confirm the item is not notforloan, damaged, lost, or withdrawn
- place 3 holds on the title
- go to the holds ratio in circulation, confirm your title shows when the ratio is set to 3
- go back to your item, set it to lost
- reload the holds ratio, see your title is no longer listed

In the scenario above, we end up dividing by zero because there are no available items. This messes up our ratio and makes this title not show as needing more copies, even though our ratio is definitely less than 3 copies per hold.
