So i've created my own tekkit server with one flaw as of now. When i enter a nether portal it no longer takes me to the nether but instead takes me to a world similar to the overworld only the sky is red and there is uranium everywhere and the only way i can see to get out of it is to disconnect and reconnect. Can anyone tell me why I cant get to the nether, how to fix that, and what world i keep going to?
