I was playing Halo 5 yesterday and ran into a bug. Every Once in a while I would be teleported to my position from a few seconds ago. I have lost kills from this. Please find a way to patch it.
That sounds more like a connection issue than a bug.
Like N7 said above - that’s more than likely a connection based issue.
Might be worth checking your network connection on Xbox and seeing the results. If you’re got a bad connection it may be worth restarting your router or plugging in a wired connection.
