I am unable to use any of my exp, raredrop and meseta boost tickets. this includes the triboosts and even food items. The "use" option is simply greyed out so i cannot access it. Is this a premium thing? does anyone else have this problem? i cannot find an explanation in game and would appreciate the help.

You can only use them when you are in the Gateway Ship or in the field. You cannot use them when you are in the Lobby, Alliance Quarters, or Personal Quarters.

Thanks alot, bud.
