Can't build conduits in smoothed stone walls.

I know it's balanced that way(Or thinking it is), just still irks me. I like the +1 beauty, but I also like power...

Put it in another wall make one line of stone walls you made for power lines, it loses +1 beauty on that section of the room boom fixed.

You can plan your base around it or you can get the hidden power conduit mod (requires research tho)
