Uhhh My NVG's are broken

[UselessHeathen]

So I got the game and the patch, proceeded to lay waste to the tiny nation of Algueria, and after hitting cgl 7 (IIRC) I found some PVS-7B goggles in a shop. Bought 'em up quick, and then night came. When I clicked the NV button, the ground turns black and the sky turns green and i can't see a damn thing. This game seems like it was built on Brigade E5, and the NVG's worked fine then... Is this a known issue? If I knew how to take a screenshot I would. Its odd, and it makes it impossible to fight with night vision. Any ideas?
