"Quaternion to matrix conversion failed" after exporting project

This line appears in the console right after building my project:

Quaternion To Matrix conversion failed because input Quaternion is invalid {-0.000000, 0.000000, 0.000000, -0.000000} l=0.000000
UnityEditor.HostView:OnGUI()

Why? :slight_smile:

Ok, it was a prefab I changed in the Project but not in a scene. XD
