Upon further testing it doesn't create a spi under me it just abruptly aims the TGP at the ground right below me.
Attached is the a track file showing the bug its on the weapons practice mission on the Nevada map
Seems to happen more often with the narrow FOV.
I've double checked my bindings and nothing is double bound. I don't think a double bound key or axis would abruptly aim the TGP down like that.
Bug.trk
