Comment (by boonebgorges):

 Thanks, @dcavins! A couple more things (one of which is caused by my
 previous suggestion ;) )

 - In `BP_Groups_Group::get()`, you're checking to see whether `parent_id`
 is `null`. But the default value you're passing through to the rest of the
 chain - `bp_has_groups()` etc - is `false`. This is going to get converted
 to a `0` for the query, which is not what we want. The null value should
 either be `null` or `false`, but it needs to be consistent.

 - In `bp_groups_update_orphaned_groups_on_group_delete()` (and maybe
 elsewhere?) you do this:

 {{{
 $grandparent_group_id = ! empty( $group->parent_id ) ? $group->parent_id :
 0;
 }}}

 We should enforce that group objects have a numeric `parent_id`
 (`populate()`). This way, the only way `parent_id` could be `empty` is if
 it's `0`, in which case you can skip the check and say
 `$grandparent_group_id = $group->parent_id`.
