Steps to Reproduce

1. Made an immersive portal that connects my house to the nether.
2. Make vanilla Nether portals in the same chunk on each overworld and nether, for your trains ofc.
3. Go through the vanilla nether portal.
4. Go Back Through again.
5. Sit and wait for chunks to load indefinitely or /kick yourself, or kill game.

What You Expected

Do the normal portal thing!

What Happened Instead

You get a infinite loading chunks glitch till relogging. Also another thing to note is if you do this and return to the nether/overworld in a different chunk, the chunk that the immersive portal and nether portal is on is a big void in the world until relogging, stepping into it will "capture" you or make you invisible until Relogging (Dont think it makes you invis to other players.)
