Heroes shattering their own fortress

I'm playing with the new 0.4.5 complete version, but I think this is happening since
always: Tunnellers shattering their own land trying to attack you.

If I were a captain sent to a hostile land and I have a fortress, the last thing I
would is demolish my own territory (aka walls).

The image is from level 3 "waterdream Draw". In this level they dig though part of
their own land; the fortress seems destroyed before I started conquering it.

The main problem with this is in level 17: Mirthshire. In this level there are some
hero portals surrounding you. There are some open doors so the heroes can go out, but
you can't go in at least you destroy the doors (so the player does not know what's
behind the doors).

Last time when I played with keeper FX 0.4.4 the heroes sometimes diggin the wall,
so the door is destroyed and your imps go there.
