I havent logged in for a few weeks. I'm currently on a month long trip to NY and am playing on a different PS4 than I was a few weeks ago. Now that I've logged in, I cant equip my level 50 Black Mage gear. It says that its not valid for my current class, even though I'm using a THM BLM staff and nothing else. What gives?

I've also lost all of my equipment sets.
