I’m adding yaw input, not setting it. Also that works great, but problem in other. When I’m applying moving it will stop to rotate.

An actor always faces direction of travel. It would basically have to move in a combination of sideways/backwards/forwards to keep facing the cursor. This is not really a solution but an explanation, sorry 
Maybe you could work around this with LookAt. There are others having the same issue, so this might be the solution.
