1. At the beginning of your (allied) turn click on a hex contained a visible German sub (e.g., #1 in the first screen cap below).
2. Then click on the game options box (#2 in 1st screen cap).
3. German u-boat flotilla disappears (#3 in 2nd screen cap).
4. This was confirmed by moving UK DD in the previous location of German flotilla (#4 in 2nd screen cap).
Seriously though, this bug is repeatable and I feel very fortunate to have stumbled across it before release.
