Hi, I had problems finding a good title :/ Anyway, I'm trying setup some Account Upgrades for my forum but I have a problem. Now all my users need to apply to get the default rank so they can actually use the forum and play on our game servers. Now I use @Brogan 's Permissions across multiple user groups now the problem here is when a user wants to donate for a higher rank the Secondary Group is changed BUT our servers check the database table Secondary_group_ids to see what rank they have, and when they donate the system only adds a group it doesnt remove or change the existing group since you can have multiple groups active. I want to prevent users from having certain groups together. I know the Account Upgrades system has the option "Disabled User Upgrades" but then they will have to have a specific upgrade active already when they are accepted, and that means I have to either give my Mods the permission to add Account Upgrades or I will have to check all the applicants my self. If anyone has a solution I would be much grateful!
