Hi, I think I also got same problem. I defeated NPC Horon. Then, I caught Darkrai but I am not allowed to use the locked IV reroll ticket at " npc spirit-seer esmeralda ". Can u help me , sir?
I am sure that I only use 1 Locked IV rr after I finished hard mode Gengarite quest.
Please,
Thank you very much! @HappyMango
