The Dice Service migration from the KenWare site to the Brick Mill site did not happen on the 17th as I planned. Last minute testing revealed some bugs in the user interface and a bug in the years-old code in the original implementation. As to the latter, the bug only shows up in an impossible game situation where Roman armies are in a battle against an army of mixed infantry and cavalry. Even so, according to the letter of the rules, the implementation had a flaw.
I have now fixed the dice service code and the Britannia resolver to my satisfaction. The migration is now set for Wednesday, the 20th.
