I dunno anyone else who has this glitch BUT:
I have an issue where randomly my auto translate stops working for gear you have to see recently. (ie I gotta look at a maple wand before I try doing "mapl" then tab for it to be on the list).
I'll look at the item, examine it, equip it, do everything, but can't auto translate. This will happen to all items.
The only fix I can do is to completely quitting the game, then logging back in from the start.
