ragdoll mover (sandbox)

hello guys, i know that ragdoll mover isn’t a native tool in the game but is one i find the most useful (also joint tool) but sometimes ragdolls didnt respond at it, and i get “something creating errors” when i use ragdoll mover on them (1st example is exella from resident evil) i can’t pose them 'cause i lose the ragdoll mover’s interface and i keep getting error till i undone the ragdoll… sadly if i freeze the ragdoll somewhere with phisycs gun or “stand pose” i can’t move limbs with joint tool and that makes some models forbidden to me…
is there any way to fix it?
