User ids array is coming empty on edit user page. I create a user group, select users and save. Its perfect but when i go to a specific user which is already in a group, checkbox(es) are not checked. Its working fine when i use edit-flow usergroups but when there are multiple groups listed on edit user page so there is a problem.
I have checked the code, i think problem is near to $usergroup->user_ids = array();
Have a look into it, i will get back to you for the fixed version.
