Please add back: "lp user group add/remove "

It was randomly removed from the newer version of luck perms. I need it because I have a ton of purchases using that command for my global ranks and there is no way I can change it now.

It wasn't randomly removed, it was one of many legacy aliases that shouldn't really have been added in the first place.

Why can't you just change them?

Essentially, if a player has already purchased a global rank and has not joined the server then the command won't process, so those who haven't joined all the servers have commands pending and I don't think I can change pending commands with buycraft

I'd consider contacting their support

An alternative is to downgrade to version 4

There was a reason this alias was undocumented btw. And yes downgrading temporarily to a v4 and then changing the commands and upgrading back should work.
