Buggy import of partial animations (Blender)

Question

Hello folks!

I'm having a lot of fun using Unity with Blender, but recently, I've stumbled upon an issue, the solving of w$$anonymous$$ch seems to be out of my reach. It's about the animations going coo-coo.
I import .blend files instead of .fbx files and I have every animation stored in a different blender action. All nice and tidy. It works just dandy... except for the partial animations.
You know. It's those animations, that only move a part of the armature, the ones that you use to augment the idle state or to make a character shoot w$$anonymous$$le he runs/walks/stands. Every animation that doesn't use all the bones in the models armature, seems to inherit the positions for those bones from the last frame of the proceeding action (alphabetically). For example: after a run animation, the next one in the actions list is a spit animation (character shakes head to spit), so instead of just a spitting head, I get a suspended-in-the-air-w$$anonymous$$le-running position and a spitting head.
That's just mad!
Now, I know I could exclude the lover part of the armature with AddMixingTransform, but the movement starts from the spine, so the arms would be affected still. Plus: that's not a real solution.

So, does anyone have any ideas..

...Pleas?

Hi, problem is because part of bones don't have keyframes, it's recomended to give them to every bone so unity or even blender will know in what position leave them when animation is ending or starting. For example:

Action 1: Hand moving (waving to people).
Action 2: Only legs on walk animation (no keyframes on hands).

If you play second after first your hands will stay on waving position and you will walk also. To prevent t$$anonymous$$s you can use Avatar mask: http://unity3d.com/learn/tutorials/modules/beginner/animation/avatar-masks?playlist=17099 But if you keyframe even empty keyframe to bones w$$anonymous$$ch you are not using, when you start Action 2 your hands will not be in Action 1 position.
