So, I have 4 servers connected to the same database and they are called: lobby, practice, skyblock, factions. The thing is when I do for example /lp user AleXutzZu parent set owner the rank is applied only on lobby, practice and skyblock but on factions I remain the same. Why?

Check, if BungeeCord and IP-forwarding are enabled on your Factions-Server.
You can find this options in the spigot.yml

IP forwarding was already enabled, I missed the bungeecord part lol. Yeah everything works fine now

Thanks!
