Can't equip weapons anymore

I am a hunter/fighter class. All of a sudden I am unable to equip my Jutus lamina, jutus crys, jutus lanse, and sigma bastad. The only weapon I was able to still equip was my golem bluffs.

you probably unequiped your mag or if you have more than 1 mag in the same character you choose the wrong one

Tsk, the true Arks Operative uses only their fists.
