I have observed that taking Tunis increases the Axis supply points by 10. Is this correct? According to the manual it seems it should be 2.

Just done a hotseat. It is 10 supply points. How odd.

Just found this in the manual on page 552:

15.2 GS v1.07 Change Log....

Changed the supply status of the Tunis port to 10 so that axis units may hold out longer in North
Africa by controlling Tunis.

These are the correct values:

As you see Tunis is worth 10.
