France'40 Gold problem

[Green]

Just guessing but the lack of movement may be by design, to ensure the garrison is tied to the fort. In the OOB file it shows the Fort de Tancrémont garrison as having Speed '0' and Unit Class 'Foot'. But the Parameter Data has a default Foot Speed of 4km/hr, so perhaps it is this default that shows in the unit data for all Foot units and not the actual speed used by the game. In a similar way, the movement allowance of 21 may simply be based on this default. So I suspect the engine is fine but the display is wrong (or at least confusing).
