Currently experiencing a strange glitch!
Slot remained locked well past the point it would be unlocked-- but, npc still displays on field when placed specifically like so in my inventory. It still battles as normal-- but just will not move to the “locked” slot. Subsequently, you lose that slot for additional stacking because it is held back in the wrong position.
