I was spectating a player driving a FZR, browsing the sounds i had for it. I clicked on load, the driver spectated and the camera went back to my XRT.

I clicked OK and then the sound settings from the FZR applied to my XRT, and whenever i go to load a XRT engine, they are now all my FZR engine presets 0.o

Picture here

how do I choose sound?

Shift+A
