I have found that Normandy '44 has two issues that need to be fixed:
US 8th corps HQ doesn’t have a “flipped-moved” side
British HQ doesn’t show artillery range
I have managed to do a partial fix.
I went into the editor and fixed and saved both issues.
Unfortunately, I could only fix it part of the way.
The changes have been updated & work under the “units” tab - but not on the map. So for my personal use, I just swapped them out and did a save game. So I use that to start new games.
It also works if you just run the “refresh counters” tool. That fixes the problems too.
I am not good enough at Vassal to fix it any further.
If anyone wants to complete the fix, let me know and I will send you what I have.
