So I recently decided to create a Prison server,and its coming along pretty good. But I am having problems with the ranking system, The cost works and it does rank up. But if lets say you have a different rank (Staff or Donor ranks) then it will put you in the group that you ranked up to., taking away your other ranks. Example If you're Helper, and you're also A if you type /rankup it'll take your A and Helper rank and just put you in B. is there anyone out there who knows how to fix this? There's also a few other problems that could be addressed, butyou will need the IP for those, Minecraft Version: 1.10 IP: 167.114.117.18:25925. I am on right now, please come ASAP. Sorry if this is in the wrong place, been a while since I've used Planet MC. <3 Thanks in advance.
