when I was doing the darkrai quest, after i entered the dark realm I accidently go to the right and exit to the dark realm. after that i try encountered a pokemon and i relog the game. when i login i was in the dark realm. After that I continue the quest and complete it. soon after completing the quest, I will catch darkrai and get a sync from pc, but when i want to go inside the alucard castle i can't go inside. After that I completed the mega gengar quest, also the hard mode and gained the reward . Next after a few days and i read the forum that I have to defeat a boss without a single pokemon fainted to enter the alucard's castle again, I try it and I am able to catch darkrai, but I didnt get reward from it. My friend that i get Ivs lock reroll after catching darkrai.
