My opponent has an Umi and Tornado Wall on the field. On my turn I summon Pleiades and bounce the Umi. The Tornado Wall does not destroy itself and when I try to attack, Tornado Wall stills stops my opponent from receiving damage.

Tornado Wall:

Activate only while "Umi" is on the field. While "Umi" is face-up on the field, you take no Battle Damage from attacking monsters. Destroy this card when "Umi" leaves the field.

Update:

I had forgotten to mention that my opponent had Imperial Custom on the field... which answers why Tornado Wall did not destroy itself[:doh:]; however I still should have been able to deal battle damage to my opponent.

Tornado wall should have stopped working as soon as Umi left the field.

Thanks for the report.

Hopefully have this fixed for the next update.
