I know this is a shot in the dark as this game is no longer supported but hoping someone can provide me with a clue to my question.
I am playing the German campaign and have run into a problem with the third scenario, Human Wave. The first turn starts of normally but after that there are no Russian reinforcements. There are supposed to be waves of Russian reinforcements but this never happens. I am very comfortable with the editor and have loaded this scenario in the editor and the reinforcements are indeed there. I looked at some old posts and read about the difficulty of this scenario in handling the waves of Russians so I know at one time this did work.
This scenario does use Events. This is showing up in the editor as Type 38 Human Wave AA Gun and Type 31 Human Wave. The Type 38 Human Wave AA Gun (I assume this provides the Germans with an AA gun) shows up some of the time (not all). The Type 31 Human Wave (I assume this is what causes the Human Wave) never shows up. I have run through the scenario numerous times. I assume theses two events are hard coded as no xls files contain anything about them. I really don't understand much about Events excluding what I have read in LnL manuals from their board games.
I did reinstall the game but that did not help.
I do not think that my words will help you, but at least I'll try.
I have only played this scenario once, and I did it a long time ago (maybe two years ago). But I remember perfectly that I suffered an authentic human wave of Soviet soldiers. I sure that the Russian reinforcements works, do not hesitate.
Also, I remember reading the message "They're too many! Fall back to the secondary positions." Examining now the Excel Script file I verified that it corresponds with line 21, that is, Event # 113.
However, I do not remember seeing the event "Type 38 Human Wave AA Gun and Type 31 Human Wave". It also does not exist in the Excel Script file, so it is very likely that "theses two events are hard coded as not xls files" as you are also thinking.
Finally, although I imagine that you have done it, when the original "Heroes of Stalingrad" program is installed again, you have to update the code (I'll copy an image of what I want to tell you).
