Everytime I join I get booted almost instantly with a message saying I don't have access to some command. I've never had a problem before and I'm confused as to why I can't join.
Have you made any changes to your mods recently?[DOUBLEPOST=1480941256][/DOUBLEPOST]Which server are you attempting to join?
Just going to throw it out there, a friend of mine is also having this issue joining the lobby at hub.mineyourmind.net. He has tried to run versions 2.5.4 2.5.5 2.5.6 and the recommended option, as well has reinstalling the pack through FTB launcher.
