last exception "get_joint_transform_from_rig"

[mos_]

hi! would be thrilled if somebody could try and help me with my last exception file  

the game doesn't crash or anything when playing the sims but after a while the orange box appears and it annoys me haha. 

i've been trying to fix this for some days now, removing my ccs and putting them back in the game to see which one is causing the problem but i don't seem to understand what the f is wrong.

when pasting the last exception file on lastexception.com it says:

"Animation Missing Transform Joint Error

An issue with the animations rigging system.

An animation failed to find and use an object slot on the animation rigging skeleton.
In most cases, you're safe to ignore this error."
