Minecraft possible Nether Portal Loading Issue/Bug

• Whenever leaving the Nether through the Nether Portal, it takes forever to load. I end up having to close out the game entirely and reload my world. After the world has been reloaded once, it loads me back into the nether about 10 - 20 blocks away from the portal. I then proceed to go through the portal again, and the same thing happens again. Closing out the game a second time, then loads into the world and is back in the Overworld but about 10 - 20 blocks away from the Nether Portal. This has also happened to someone else I was watching on Mixer.
