Since the most recent update, everyone on my server is having issues with nether portals.

>Go to use the portal>get stuck in a loading screen> log out > log back in and you've been transported to the exact same coordinates of your overworld portal, but in the nether.

IE. Going into an overworld portal at x1000, y100, z1000 and you'll come out in the nether at x1000, y100, z1000, despite having created both sides of the portal.

This is making nether portals completely unuseable.
