I've now upgraded the Brummbär Vassal extension to include the new trio of Sicily scenarios. You can find it here - Memoir '44 Vassal: Brummbär extension version 0.6
You will need to download it to your extension folder replacing the Brummbär extension that is now there.
Let me know if something is out of place. I haven't worked in Vassal for a month or so now and it seemed too easy so I'm sure I did something wrong.
