I just started to lear use the program and everything's right except a legallity check with a feraligatr, it seems it doesn't have Avalanche as a valid move when it was an avaliable TM to learn in Gen4 and the game origin is HG
It seems it's just missing because I have no problem with other combination of attacks from older gems like Golem from Emerald with Sucker Punch from Gen4 tutor
Thanks for all
