Clearing rubble problems and bug.

[Ricky B]

And by the way, I cleared a few rubble hexes in Kiev, right inside the city where having the roads clear were important. They took around a day - although in Bulge years ago, I tried to clear a critical rubble hex on the initial front lines and never succeeded - back then I wondered if it worked at all - it does now but no idea about back then. Or quality adjustments may be poorly handled and reduce it to a rounded down 0 and so never happens for bad engineers???
