Attaching entities messes up their rotation

[TheMuggles]

I've been trying to figure out why using ATTACH_ENTITY_TO_ENTITY seems to mess up the rotation of an object given. It seems as though I can't change an entities rotation and then attach it & keep its rotation. This is how I am attaching the object:

ENTITY::ATTACH_ENTITY_TO_ENTITY(obj, selected_entity_to_attach_to, 0, relative_coords.x, relative_coords.y, relative_coords.z, creatorObject[obj].rotx, creatorObject[obj].roty, creatorObject[obj].rotz, 1, 1, 1, 0, 2, 1);

Am I doing something wrong here with the parameters? (I'm basically just trying to get an objects rotation to save after attaching it to something).

Thanks.
