When playing on a server pushing a button next to powered rail activates correctly and gets the mine cart going but a couple seconds later you instantly log off and it claims the server closed I own the server so i have restarted and retried this many times. On the last snapshot you would simply stop and restart your client but now it crashes the server. I have looked for a while and found only one issue similar to this it claims that chunks stop loading when riding on mine carts. I'm not sure if this happens in single player, I have not tried it yet. Thanks for reading this.
