DD-AI in Kari Mar digs into hero cache and gets dungeon destroyed

What game elements does the new feature/behavior concern?
-The Kari Mar level has it's issues, and I'm not talking about the overzealous 
trap/hero cache placements.

The problem I'd wish to point out here is: The yellow Keeper AI is so stupid 
that it digs into the small cavern with the high levelled Samurai/Monks (near 
the graveyard) rather soon, whom just destroy the Dungeon heart with no 
resistence. This causes a super-easy unintented level victory, while the player 
doesn't have the know what's happening.

Where exactly inside the game should it be accessible?
n/a

Please provide any additional information below.
I would recommend making it harder for the yellow keeper to dig into them 
accidently, but other than moving the section upward (or remove the gold just 
to the south of it). Otherwise, lava or a reinforced wall should prevent this 
from happening. Cause it's not quite possible to restrict the AI that easily, 
is it?
