Unsimulated walls don't properly block air

Created by: clusterfack

I believe this is a result of d3athrow's catwalk changes to ZAS. Unsimulated walls allow airflow towards/through them for some reason.

You can check this by opening a plasma canister in the thunderdome for example, an item or mob will be jostled around by airflow towards one of the unsimulated walls and collide with it.
