PhysicsAsset (Phat) torn joins

Hello everybody. I have a problem with physics asset. On the dummy, the joins are torn. Profiles set up exactly as in robo recall. Everything is shown on video. What is the problem, can anyone tell?

robo recall 4.16, my project 4.19.1

my project test in 4.16

All settings from the robo recall.

I don’t know, may be it’s bug?

I will be glad to any help.

My problem was solved by the setting “Position solver iteration count”.

With other bones this is not done.
