I have encountered some problems "which may require me to redo most if not all animations" for my latest character.

Let's me explain the issue.
I do the animations for like "tongue out". I only touch/add keys to the specefic bones needed for this task. After export to collada all of the bones in the whole skeleton eventually ends up with a animated key "like if i would have touched every bone every fram i did something". The "untouched" bone's key frames only have zero cordinates which wont cause them to move. But all bones having keys in every animation file causes some issue witch messes up my whole latest character if i add in specefic animations like this.

I didn't have this issue with the exporter half year ago. But i got some updates to blender since and i think they broke something again with the exporter, or changed some settings i dont know about. My earlier exports for older characters didn't get a key on every single bone after export so this is new for me. Earlier they only exported the keys i did. Im not even sure what is causing blender to add all of these zero keys but i know they wreck something.

Would really like to know how to fix this.
