Elaborated description:
Warping to the Nether from the mine world currently goes to the previous mine world's Nether. Going back into the portal brings you to the main world.
Is the issue persistent?
Yes.
Additional information:
When we were doing the changeover, I noticed I could get to the new Nether from the old mine world, before it was reset.
