Brummbar's version is version 7?
Yes I think it is: http://www.brummbar44.com/vassal/
But some hexes have up to 4 units stacked on top of each other which aren't discovered until you try moving or taking hits. This is a common problem if you try to clone units instead of grab them fresh from the pallette.
This is a common problem. I run into it too. It doesn't affect gameplay very much though. There are a few of those in v7 too...
Another issue is the special forces badges were placed over units. This prevents you from reaching the right-click menu of that unit to take hits, place markers on them, etc. The fix is that you have to double-click the unit to separate them, then restack them in the opposite order.
Yes that was a common problem too. I think we checked al the unit's with badges in v7. I actually placed all the SF markers and after I placed the units over them.
I know there were also a lot of problems logging on as certain sides. Most likely this is an error with Vassal instead of the module. But this type of error can occur if someone logs on to a side and forgets to retire. I personally haven't experienced this but some of my opponents have in live games.
I have only played live games and I never had that problem.
Anyway Memoir '44 is a great game, and I play it in any chance I get!
