After nether travel, my compass is pointing to the wrong spot, about 300 blocks away from my actual spawn. I traveled to another area via nether portals, and my compass was pointing in the wrong direction. However, the spawn point itself is not affected, tested after destroying beds and killing myself. I fixed it temporarily by dying, or by re-logging.

What I expected to happen was...
My compass to point to my spawn point that I only remembered the general vicinity of.

What actually happened was...
My compass pointed to a spot about 300 blocks away in the middle of an ocean.

Steps to Reproduce:
1. Create a compass.
2. Use a nether portal to go to the nether.
3. Return to the overworld and witness a messed up compass.
