Changes between Initial Version and Version 1 of Ticket #7677, comment 6

initial	v1
1	1	I may have found how the admins were removed: as part of an integration with an external membership database, we call BP_Groups_Member->demote() on users when certain conditions are met. It doesn't appear to me that this tries to manage the fact that the group may be left admin-less afterwards. Did I miss where that's handled or is this the aforementioned separate bug?

	3	groups_ban_member() works differently and doesn't actually modify the user if they're an admin.
