May be related to: When bulk inviting users to a group, user profile settings do not reflect the fact that the are part of that group
…but I looked at the pull request and am not sure. User profiles in admin are not showing their custom group memberships, even though the database appears to have them. If I try to add them to a group I know they are already in, I get an error like the one in the above-referenced topic, however if I add them to a group in which they are not a member, the UI does not reflect this. I am on v1.3.0.beta5 +13.
