At first, sorry for the bad english 
Hello there, it's a best mod since Desert Combat for BF1942  .

Nice work guys.

but now for a buggy things:

When i driving (when im a driver)  by a quad or by an pickup (any models) and i turn left or right i ve an "Diashow effect".
By another fehicles it works fine for me.

Is it a bug or a feature ?
Has any1 the same probs?
How can i fix it ?

Thanks a lot

EA's patch hope the new 1.3 fixes what they messed up with the 1.22. Seems like they can't do anything right. N@W version 4.0 will be out shortly so just bare with us and just maybe we get it all fixed.
