I was with you on this one. It was buggin’ me quite a bit until the fix went through! Typically most morph targets I’ve used with testing or in my personal projects have been just a mesh and not character related. 
If you want you can post a link here or send me a link via a private message. It’s getting a bit late for me, so no promises on an answer tonight, but I’ll look at it as soon as I can.
