Yo. So I'm doing a randomized playthrough and have just made it to the Victini Quest in the postgame. You need to collect certain items off of wild pokemon that, for obvious reasons, I cannot obtain. The only item I'm missing for the curry is a berry juice from a Shuckle. And it just so happens that I found a shuckle as one of the legendaries in one of the last quests and did not catch it. This means I have no way of making the curry and no way to turn the randomizer off... any help?
