France'40 Gold problem

[krmiller]

Playing Scenario #0510_01B3 Fall Gelb and have found a problem with some of the Belgian forts.
The Garrison in Fort de Tancremont in hex 350,220 shows Movement 21.  The Info side shows a speed of 4 which would indicate it could move.  However the game will not allow me to move it even though it is no longer Fixed.
When I try I get 'Unit is not capable of movement".
There are several other forts in the Liege area that also show movement of 21 but they are still fixed,

Meanwhile the Garrision at Fort de-Aubin-Neufchateau hex 347,202 shows a Fire Ability of 3 as does Fort de Batice in 351,210 and a speed of 0 which would indicate it can't move.

I understand a Fort not being able to move but not the garrison.
In any case something is wrong with the unit display or the engine.
