I am in the settings tab of my fleet and selecting the check boxes for my second in command rank and then when its done i click on the rank below it and it has all the boxes checked that i checked off for my second in command.
Anytime i remove a checkmark or add a new one it copys it to all the rank pages?
It was doing that for us as well. Also, for whatever reason, when my bud made me Captain, second rank below top rank, I couldn't talk in fleet chat, kept saying Not in fleet. I had him demote me to third in command and it worked again. He sent a bug report, hope that gets fixed.
