The log entries that show a Prussian garrison foraging to death in Nuremberg say "337" instead of "Nuremberg". Part of the log for the Prussian turn is duplicated.
I (France) have no troops in Russia & Prussia barely has any troops in PRUSSIA [:'(]
The log entry with the 337 is probably not trying to refer to AREA337; my guess is
that you have a string that isn't getting set someplace & the "337" is just the
leftover garbage from whatever was in that variable.
