when i traded in olive city even after updating the game to latest my game crashes :(

happened to me as well, houndour is being a bad dog 

worst part is as i want to complete the game(as in get every mon evolve every mon do every trade etc. etc.) that bug prevents it :( 

U can still catch a Houndoom at Mt. moon and then breed it with Ditto to obtain Houndour. Gl guys.

IK i can get houndour via breeding but as said 100%ing also means all trades ingame
