New bug. Well, probably not new, but first time I have seen it.
The picture says it all: It's the British naval phase, and there is a corps counter in Amsterdam, yet the Holland fleet counters are both still there. They should have attempted to evacuate before my naval phase.
I've included the current save files, plus the saved reinforcement phase files, so you can see I really did own it prior to my naval phase.
By the way, I think you should re-think how evacuations are handled. In the original game, they occurred instantly. There really isn't a good reason not to maintain that tradition. Yes, I know, they get conquered in the land phase. But, you can still add a naval combat item. It would just be another file to upload (along with the land movement and land combat files).
I am sure that this bug did not exist in the original 1.0 version of the game, it's new to 1.0.1. I clearly recall taking ports in 1.0 and having the fleets evacuate immediately, however in 1.0.1 there seems to be a delay -- sometimes until the next diplomacy phase.
Oh, yes. In fact, in this very game the same thing happened in three other ports, and they all worked the way they should. So, whatever the problem is, it is inconsistent.
At LAST! The greatest campaign board game of all time is finally available for the PC. Can my old heart stand the strain?
