I was at trainer's tower recently and faced a peculiar hurdle. According to the description at desk, it said that no trainer would use a pokemon type that's strong against mine
with the exception of diverse rooster. But according to the situation, i bought only flying/normal types yet still faced a disadvantage typing
As you can see, i have 6 starlys in my rooster yet faced a macargo which is fire/rock type, which proceeded to wipe my team.
If this is a bug, please fix it soon and if not, please revise the trainer's pokemon generator to match desk description.
