Greetings Chosen_One and dorusoftware, thank you for posting your query to the forums.
Your concern sounds like you may need to add some constraints to your physics asset. If you do not already have constraints set up in your physics asset, I would see if adding them helps a bit.
I have found a YouTube video that goes over how to set up constraints, limits and much more if you are interested.
