News updates would suggest that this version of the Stuart was made more 'recently' as a vehicle strictly for Sidi Bou Zid, and then Pointblank decided to make a Pacific skin for it for some reason. Another theory could be that Pointblank made this version of the Stuart for a Pacific front that was scrapped long ago, and he reskinned it when someone created a map it could be used on (a la Sidi Bou Zid). Another theory would be that the truth is something completely different
Less drastic conspiracies: there have been Shermans and other vehicles with 1st Polish Armored Division markings in the files for some time. Mt. Ormel map still being worked on?
