How to reproduce the bug:
1- Release a pokemon.
2- Open your pokedex, and try to open the info for the number 200, even if it's unknown (also any number around it, like 199 and 201).
3- You get automatically into someone TV channel, even if you aren't near a TV.
4- Your pokemon will appear at the person's screen. You can even use your moves, but they don't do damage if you target something. You can also give orders like t1, t2 and your sentence will appear in the screen (like "Maritos says: Pokemon, turn north!").
Also, a certain number in Pokedex is related to a certain channel in TV's list. That means, some numbers can lead to a TV channel, some can't. And each number takes to a different channel.
