Wulfir, I have completed Uściług scenario you made, made my record when we combine casualties.
Unfortunately, German AI seems to have SERIOUS issues with behavour what probably breaks that scenario - Germans constantly advance along the river with super low speed, probably due to VP placement. Also, entire northern armoured group seems to be stuck and just standing there for the battle entire.
I am attaching some screens. You may want to take a look onto it. Here's the link (it allows greater image size than forums):
