Please stop talking shit..
Let me proof something, i'm going to summon 100 super balls and 100 defeated squirtle corpses, to proof that people is only talking shit.
12:40 You caught a pokemon (Squirtle [21]). But you are already holding six Pokemons your pokemon will be teleport to the pokemon center! -> First squirtle took me only 29 Super balls (71 balls left)
12:42 You caught a pokemon (Squirtle [21]). But you are already holding six Pokemons your pokemon will be teleport to the pokemon center! -> Second one took me 30 Super balls (41 super balls left)
Ok, now i used my last 41 super balls and didn't caught any.
Let's try again with 100 super balls.
12:48 You caught a pokemon (Squirtle [21]). But you are already holding six Pokemons your pokemon will be teleport to the pokemon center! (42 super balls left, so i used 58)
