I'm looking for a hostgroup in my foreman instance, there are some hosts that appear as belong to that hostgroup but the hostgroup doesn't exist anymore - I can't find it in the list of hostgroups, even not by search-by-name, when editing a host that belongs to the aforementioned hostgroup - the hostgroup field is empty.

I'm trying to find out what happen with that hostgroup, I've searched the hostgroup name in the audit log and I could only find its creation, I would expect to find its deletion or renaming but there is no such audit entry, so I'm not sure whether the issue is the hostgroup disappearance, it might be the audit log's absence/search.
