I do not know if this is a bug, but it appears like one to me.
When an imported character is too small (couldt find out from which size on) and you import another object, for instance an obj eyeball as accessory, them move it around, scale it etc. all over sudden the gizmo inverts intself into the wrong direction. So when usually when pulling the mouse , beginning all the way from the left to the right, an object usually rotates into that direction, the gizmo begins rotating the object into the opposite direction. This happens sometimes directly after import, sometimes after the object has been placed, all over sudden and cant be reverted until you start a new session.
