Describe Your Issue

This was tested on a fresh instance with just MRU, RSLS, Sounds, and YACL (was required despite not being listed on Sounds' Modrinth).
Adding 1.1.8 to the versionRange for rsls makes it happy and launch fine

Steps to Reproduce

1. Install Sounds and Raise Sound Limit Simplified plus requirements
2. Launch game
3. :(

Will be fixed in the next update. Thanks for reporting.

Not sure if the above person got the exact same error message, but my error message said:

Mod sounds only supports rsls
Currently, rsls is 1.1.8

So, clearly I have rsls installed, so why is it complaining?

I have the same issue for Neoforge 1.21.1
