Enemy archers can shoot through iron doors

I don’t if it is a bug, but enemy archers can shoot through iron doors.

This makes defense a really annoying task.

It goes both ways: your archers can also shoot through doors. It is a little silly.

I would assume that it’s a bug, I mean what are the ogres there for anyways?
At least it’s an even bug.
