World: 'Underworld', Level: 'Children of the Damned', Difficulty: 'Normal'

Playing this level is not a problem, until the final "boss level" of enemies appear. For my account (and after several attempts to complete), the option to attack never loads when the final round of enemies load, and my team is stuck staring the enemy face to face... breathing and staring... into infinity.

This would not be much of an issue if not for being the last "skulls" necessary to unlock the secret level in the Underworld on Normal difficulty.

Transmitting this message to any/all who are capable of adressing such issues. Thank you for developing this wonderful game.
