Issues with vanilla dimensions

I have an issue with spongeforge-1.10.2-2171-5.1.0-BETA-2010
I’m using the Skyexchange modpack with forge 2171 for minecraft 1.10.2.
When i have spongeforge on the server, without any plugins nether and end portals do not work.

  • If i remove the spongeforge jar file everything works fine.
  • Sponge gives no logs at all when i start the server.
  • My dimension.conf file is unedited with world_enabled = true .
  • If i go to the nether, log out and then install sponge i get teleported to spawn in ‘world’.
  • Other dimensions such as the deep dark seem to work fine.

What does your server.properties file look like?
