With Immersive Portals, Nether Portals have been disabled and dimension stacking has been enabled with the Nether and Infinite Abyss dimensions. Unsure if the settings for the stack will upload to curseforge with the mod. The Nether and Infinite Abyss dimensions required some setting adjustments in Immersive Portals setting on world creation. This has been set up already.
Create and Immersive Portals have some issues, but from testing it is mostly trying to get trains/create contraptions through the immersive portals. Just avoid this.
