A repeated issue I've been having is, after my Nether trips, the world seems a bit more sinister...
It's because the background wind of the Nether just doesn't stop lol (even when typing this it's still playing on the alt tab lol)
I think it's because the mod constantly plays music to match console, but I think it's interfering with the Nether ambience from stopping.

Sounds like you're using re-console. iirc Legacy4Java doesn't continually play music. Re-console uses the Infinite music mod for their modpack. Have you tried using just Legacy4Java to see if the problem still happens?

Maybe try disabling/deleting the infinite music mod within the modpack and see if that fixes it too?

I'm not playing re-console, just Legacy4J
I might've been mistaken about the constant music, because that was a "sales pitch" I heard before I got the mod lol
When I'm not busy I'll see if turning off somethings prevents it.

Can confirm, getting the same issue with only Legacy4Java installed. Very eerie!
