Stop Ragdoll

Hello, I created a ragdoll combat wtf game. There is a special attack, which is when we click right, our character is expelled forward, and after 3 seconds, stands up. Everything works fine, but when he gets up, he is expelled upwards to infinity! I can not fix this bug, I looked on full forum, nothing.

Help me please :frowning:
