IndexError: tuple index out of range

When: From what i noticed the error happen at the begining of the combat (before the bot get to pick an pokemon to start yet), when enemy team got 2 duplicated pokemons (for example Urshifu and Urshifu-Rapid-Strike)

Duplicate of #3

Yes this will cause an error. The bot will error if either team has two pokemon of the same species. This means that certain formats that allow this will not work.

Closing due to being a duplicate of #3.
