Im having an issue with Pex and buycraft. When someone purchases a donation rank, They lose the ability to rankup. Which is weird. And i dont know why this is happening. This has happened with everyone whos donated. The command im using is pex user {name} group add <group name>. This only happens to people who purchase ranks. I dont want to publicly release my ranks, So please PM me or post here for them, I hope you understand, Thanks! I made a thread about this earlier, but i figured that out, now i am having this issue.
Erm i think the command you might want to be using is /pex user {name} group set {group_name} That should fix the problem
