When a bomber bombs a one-way wall in the opposite direction, the wall explodes anyway (e.g. if a lemming bombs a one-way right wall from the left side, the wall explodes).
I don't see the logic behind this. If one cannot bash/mine in the opposite direction, then how come bombing can?
However, if this does get changed so bombers cannot bomb in the opposite direction, I can see this can potentially break a lot of levels. If this doesn't get changed in the end, I won't mind. I just wanted to see what other people think.
