XEEN: character sheet stats don't update properly

[darkstar]

When changing the armor of a character, the "AC" stat (and possibly others) don't reflect that until another character (or even the same character) is selected again.

To reproduce:

Start a new game, press F2 to view the character sheet for Tyro, note the AC value of 10, click on "Item", click "Armor", select the scale armor and unequip it (Press 1, R), then close the equipment dialog with "Exit", note the AC is still 10
Click on the AC icon and it says "6/6" (see attached screenshot)

When you press F3 and F2 again (or even just F2), the AC is recalculated properly
