that is a sync issue with the server, either due to lag on your end or their end.
bug with starting positions?

check your internet connection. ie, reset your router/modem, run a speedtest on your mobile device/computer. if you're playing from a mobile device, try playing on a computer and see if you have the same issue or vice versa. if it messes up on mobile but works fine on desktop, try reinstalling the app on your mobile.

yeah, check your internet connection. go to speedtest.net when you have issues and see what it says. if you're on wifi, try to direct connect.
