Avatar keeps bending down after pose

[DorianaCele]

Hello everyone, my AV keeps bending down after some of my animations that moves the 6 waist joints (spine 1 to 4, chest and torso) to make myself bend down. It happens even the animation is only priority 2. Resetting Skel. and Anim. on myself solves this for myself, but other people still see me as bending down, and they need to right click on me and reset the skel. and anim. of me themselves. This is very annoying. Is there any solution to this problem? Thank you very much.

Update: I found that the 4 spine joints (spine 1 to spine 4) do not reset properly after leaving the pose, while torso and chest work fine. So a temporal solution is leaving the 4 spine joints just minor tweaks to prevent random shift, but put all bending values on torso and chest.
