Stalingrad and pontoons

[Glenn Saunders]

The issue is likely that RUBBLE negates the road movement and triples the terrain cost unitil it is cleared by an Eng.

Once cleared, Rubble still triples movement costs through the hex, but does allows road movement. Rubble that is not cleared is reported as "RUBBLE" in the Terrain Info Box while Rubble that is cleared is reported as "Rubble".

...I suspect that somewhere in this is the answer to your question or issue.
