I got this surprising result in a run through of the Tannenberg scenario today using 105a. A Russian cavalry corps got a "shaken" result (note the little lock on the unit) without also being reduced/flipped? In the LGG boardgame, and based on my understanding of the rules for computer LGG, a unit only takes a morale check if it suffers:
1. An "M" or "2" result on the CRT
2. A "1" result on the CRT, while at reduced strength
So in this case how did the Russian unit end up both Shaken and at full strength? I've noted similar results before in other battles as well. See attached.
