FixMask.cs

//saves you from agonizing manual clicking "Fix Mask" on each user-created clip, 
//when you have updated/edited the original FBX changing the skeleton hierarchy

//drop this in your Scripts/Editor folder, 
//select FBX's and right click context menu Fix Animation Masks  
//reImporot Foloder
//tested on Unity 5.3.4p3

//minor update, sets all transforms of the avatarMask to active (assuming you are just using 'Mask Definition Create From This Model' with all transforms active (Default behavior)
