[cthulhu]

Personally I think that queens of elemental air ought to be able to at least go over water even if they aren't allowed to go under water. Something similar to the sailing special ability, but effecting only the commander? Or heck, maybe just sailing.

But I agree that it's not really a bug. Unit attributes that do not show up in the icons or the text descriptions are not automatically bugs, though they are undesirable.
