This is a bug that was in the game a while ago and had been fixed. It's BAAACK. hehe. I had 3 blue yum potions on my privateer. I used a couple of them in ship fights. I flew my ship into a blue yum fruit to begin refilling my 2 of 3 potions. Instead of starting to refill the second bottle, it took away the full potion I had, and gave me the small amount that should have been added to the second bottle. If it matters, the bug happened in the port regal skyway. Hope is is fixed again soon.
