When grouping existing holds into a hyperhold or when ungrouping a hyperhold, the actions aren't logged, which is going to make troubleshooting extremely difficult (or impossible, depending on the issue). Hold groups are assigned an ID which shows in logs as hold_group_id when other changes are made to the hold, but grouping/ungrouping itself isn't logged. To replicate: -Place 2 or more holds for a patron (regular, not grouped) -Find the reserve_id for one of the holds, and view it in Tools > Logs. There will be an entry for the hold's creation. -From the patron's account, select the holds and click 'Group selected' -Run the log for the reserve_id, and note that there was not an entry generated by putting the hold into a group -Suspend the hold, then view the log for that reserve_id. Note that the log entry for the suspension now includes the hold_group_id. -From the patron's hold tab, click on the number in the 'Hold group' column, then select 'Ungroup hold' -Run the log for the reserve_id, and note that there is no new entry for ungrouping the hold
