MTN units (not) negating Blizzard

[TeaLeaf]

The Marsh hex west of leningrad.
Germans were checking the odds for attacking this hex and I found something I don't understand:

Odds are 21:4 = 5:1.
Half or more of the attackers are MTN, so this attack in Blizzard should suffer from -1oddslevel for a final result of 4:1.
However, the odds 'finalize' at 2:1. My guess is the MTN units are not negating the Blizzard correctly.

The Blizzard is also not negated if:
-The Italian unit is left out
-only the MTN units attack

This is a bug...

The program is handling this correctly.

The use of Winterized units is decided by the Attacking and Defending players after the combat has been selected for resolution. Once you select the combat for resolution, the program with ask whether the player wants to use the benefit of winterized units or not. When the answer in this situation is Yes, then the odds are recalculated and shown as 4:1.

You are right. The question to use the MTN is asked during Combat resolution...

Exactly like ENGs work. Next winterturns Russia may have a problem there .
