Not sure if anyone has had the same issue but I enabled IKTweaks and while it does make FBT *considerably* better, I notice that when I sit down my avatar's neck is completely fucked, like it's all sagging forward/slouched. Even if I try my best to force a super straight posture with my back it only partially fixes it for a second before it goes back to looking weird. It only seems to look good when I'm standing, but sitting forces this "slouched" position even if I'm not sitting slouched.

I know there's a handful of neck/spine related settings in the settings tab but going in blind is tough I tried changing a few values around but it did fuck all and I didn't even notice any changes.

Could use some help, if I can fix this neck issue I should be solid with IKTweaks
