Apparently, if you breed Encore onto an HA Pikachu, and try to breed that Pika, The game will crash when you try to receive the egg from the ranch. I have tested it dozens of times, and every time it has the same result. I have also gotten an admin to spawn me in a new one as a replacement thinking that specific one was bugged. Same result. When I removed Encore, it bred fine. If it matters, I was breeding it with a 6iv Jolly shroomish, the pika was timid, and they were holding d-knot and everstone, the pika had the everstone.
