      Description

      Entering certain chunks from West to East (towards positive X) along the Z axis causes a lag spike.

      I apologize for the lack of information, but I'm uncertain of the conditions that cause this. Playing this world regenerated with the same seed offline does not reproduce the bug.

      Edit: This bug doesn't seem to only happen when moving +X. It now occurs with random chunks and directions. Again, I have no idea what the conditions are for causing this.
