EDIT
Ok, I just created a new blank level and the issue is not happening. In the first saved level/map I had coped and pasted the tank to a few locations on the map. I don't know why that would cause the issue, it never has before. But the issue is gone in this new level I just started. However, if I pull up the old level, the issue comes back so it's obviously backed into the saved game file.
EDIT 2
Now I'm confussed, If I go back to the broken level and add the dame tank, it's now showing up as the green tank without the camo. And I know for certain I'm picking the same tank.
