Avastar Av deforms

[So Whimsy]

Morning folks, the Avastar group seems to be asleep so I am trying my luck here.

I recently upgraded my avastar version to support bento bones, now I was just fiddling around when I noticed a problem I can't seem to figure out to fix.
When I select the avatars calf and drag it around it moves the whole leg and hips as it should. But when I move the back of my avatar it moves everything above it (head, shoulders etc) but nothing from the stomach down and the avatar instead deforms. How can I stop this deformation from happening so I can once again select a certain joint and drag my mouse around to move the entire avatar at once?

When I open old animations made in the previous non bento avastar version I do not have this deformation happening (see below)

Someone please help me fix this so the bento av does no longer deform T.T

i guess the problem is the IK chain length, involving the extra spine bones that are folded over on each other. I did quit using Blender and Avastar before the version 2 was released, so i can't be sure. However, try to look for any options that let you remove the extra spine joints, if any available.

Another possible cause is the Blender version: the 2.79 version is known to have broken the previous versions rig systems, the only reliable version to use Avastar with, as of yet, is 2.78

Translations in the upper body do not work anymore as they used to, so use rotations in the upper body bones and COG for entire avatar positioning to solve the problem.
