UNET player and child rotation

So i've been trying for hours to fix this but now i have no idea what's wrong (probably everything :D) but anyway.. Here is a video: https://www.youtube.com/watch?v=X8JrXwgvvFg As you can see my player is rotating and it's synced (as you can see by text above player), but the "hand" isn't and i don't know why. Can you help me?
