I have too many questions lol...

Anyway, I have downloaded and slightly modified a newboathog from halomaps.org. The only modification that I have made to it was changing in from vehicle type "Human Jeep" to vehicle type "Human plane".

It has 1 error: Whichever way you face when in the gunner, the gun will face the other way, then you cannot see where you are shooting as it is 180 degrees on either side of you.
I have no idea why it would do that - I checked similarities between newboathog.vehicle and warthog.vehicle but I cannot find anything that would cause it.

Is there an explanation for this, and how would I fix it?

Thanks,
