The rotation values displayed in the object editor box do not accurately represent the yaw/pitch/roll of the selected object.
An object placed in eden with these rotation values
pitch = 0
roll = 45
yaw = 200
is actually
pitch = -13.9954;
roll = 44.0815;
yaw = 194.433;
when using functions gerDir and getPitchBank.
This screenshot demonstrates the difference between edens method of spawning in objects vs spawning in an object and rotating it with bis_fnc_setObjectRotation: https://gyazo.com/8eeddc371b0a74ac317f74cea7309ec0
