This is starting to really bug me.
Every time I open the Unity Editor… EVERY. TIME. my mecanim animation is completely bugged, it just refuses to work at all.
If I proceed to select the offending object (which shows the Animator component in the inspector), suddenly the animation starts working again. It continues working until I next restart the Unity editor.
Luckily I only have one Animator component in the whole project, but very soon I will have more, and it’s going to be an absolute nightmare if this isn’t fixed.
Unity Version: 4.6.0b17
