When going through a nether portal it creates another one close by.

What I expected to happen was: Me to go to the other side of the portal.

What actually happened was: It created another portal 2/3 blocks away from the actual portal, and then going through.

1. Go through a nether portal that was created by the player itself.
2. And then on the other side another portal is created just a few blocks away from the actual place you shouldve gone through.
