I found a rattata i wanted to train and tryed to teach a power with a TM. I tried to teach it watter gun and the screan to change a power popped up, but it then froze. I reloged-in and the TM was gone and the power wasnt on the rattata. I tried to teach it another one but the TM just dissappeared and it didn't let me choose a power to switch with. I tried a bunch more different TM's but they all just dissappeared. Still no power. What do I do?
