How about actually providing info?

I just clicked by accident sorry, i dont know how to delete it. So i gonna write here. I have a problem a plugin called grief defender in the last update they decided to transfer all their player info to contextual data in luck perms, the migrator worked perfectly but my server is a rankup server and when someon rankups and after that the player info of grief defender update the player returns to the previous parent. I talked to the creator of grief defender and told me that grief defender doesnt change anything about parents, i tried in a empty server and I couldnt replicate de bug. Do you know if there is a bug with contextual data of users that make this happen?

All this in this version of luck perms: LuckPerms-Bukkit-5.0.72.jar

Possibly related to #1977

Not enough info here for me to be able to help. But no, I doubt there's any underlying issue/bug here.
