After some cutscenes, not all, my first and third slot characters get completely unequipped. The most recent case of this happening was after talking to the king to get to the wind shrine. On the first map. This happens intermittently throughout the game. I am on version 1.12.

yea this happened to me too, but after awhile it stopped.. i dunno what stopped it.

Happened again right after stealing the chocobo from the rebels. Can't even equip during the event so I just had to go through it with half the party unequipped.
