cleaning rubble in Normandy 44

[bigus]

Then I've been extremely unlucky the last 10 turns.
The problem, could be scenario specific too.

The only thing that is scenario specific is the parameter data that is being used. Check and see what the Digging In percentage is. For Moscow '41 I think it is always 10%. So, each turn there is a 1 in 20 chance of clearing RUBBLE and that chance is independent of the previous chances. You can easily go for more than 20 turns without being lucky. Simple as that. I do not see anything 'extreme' about your luck. And anyway sometimes you can be very unlucky.

Parameter data is scenario specific then?
Rubble clearing is parameter specific?

Then I would think the chance to clear rubble is scenario specific or parameter specific?

Why didn't you just say so....
