The bug is that when you make a nether portal and you go in the nether and when you return the nether portal spawns somewhere else sometimes 100 blocks away or sometimes 10000 approximate blocks this happens in the nether too the same nether portal spawns somewhere else in the nether please fix this issue right away i would appreciate it 

I will provide the seed and the coordinates of my nether portal:
seed: 931608811 and the coordinates of my nether portal: 2050,64,-1467
