The mod doesnt work on forge 41.1.0 version 1.19 of minecraft
When i open the game with the mod installed a message apears saying "Mod file deeperdarker-1.0.0b-1.19.2.jar needs language provider javafml:42 or above to load" "we have found 41"

Download the appropriate file here

Doesn't work on aternos too. Same error

That is an issue on how Aternos searches for JAR files. It is an easy fix on our end, so the file will be available soon!

OK thank u, I will wait for that
