I was building a device that can teleport me using commands to different places in my world but for some reason if I teleport far away, the game has multiple bugs. this happened in a superflat world. the bugs are: movement is broken, you can't move without flying. when flying the movement is glitchy, you can't move diagonally, when trying to move when flying, you would have to keep the joy-stick pointing up for about 3 seconds and then it would respond. block breaking is messed up, when breaking blocks the little particles that it makes goes to different directions, however when teleported far away, it makes this sorta plus thing, one vertical line of particles in every side and the middle.
