As reported in my AAR last night, I ran into the situation shown in the image below. The combat result should have resulted in a shattered unit and 2 destroyed units (all should be destroyed once implement because there is not retreat path). In the image, the division is not destroyed and it cannot be destroyed. Once implemented the other two are destroyed but the division remains in the hex and prevents occupation of the city.
In the next post, I'll provide two saved games and the steps taken to replicate. Note, the two saved games are because I tried to replicate closer to the actual die rolls, but it would not. I had to proceed from a saved game before the questions on use of winterized units. Saved games after that question appeared to work fine.
