Can't fight anymore.

[Former user]

After the battle double with the man who have Kyurem and Zekrom I can't fight anymore. When a battle start, is a double battle and this message appears saying:

Script 'PokeBattle_Battle' line 853: NoMethodError occurred. Undefined method `+' for nil:NilClass

And the game crash.
