»Sometimes the Mog Safe 2 menu is greyed out when I access it through the Moogle. When that happens, I open it through the main menu > View House > Mog Safe 2.
This happens to me too... it seems to be related to loading times and opening up the menu too quickly when I zone into my MH. Generally if I fully close the menu and try again Safe 2 is able to be opened.
Regarding OP's problem, could it be a dat swap issue? Some of the packs that make the fonts easier to read needed to be updated when Mog Case/Safe2/Wardrobes were added, otherwise those options didn't exist at all in the menu even though they were accessible in game. Maybe OP grabbed an outdated pack on accident?
