I have killed all the robot waves .
there are no more robots to go.
mechanist is just screaming 'more mines' and all that..
nothing much is happening , except the moving cranes above, and every now and then dropping some bomb cannisters ...
the power shud go dn and the mechanist must have a talk , but its not happening.at all. looks like I am in this room for infinity .
of course recourse is going back to previous saved games
but this bug is serious .
