Hello! Twilight Forest progression seems to be broken when using SpongeForge. The advancement “carminite acclimation” is never granted to the player after defeating the Knight Phantom Boss in Twilight Forest. I’ve tested and confirmed it works fine without SpongeForge installed. The mod author has not responded about this issue, and the last update was in 2018. I believe this might be a bug that has to be fixed on SpongeForge’s side.
Keep up the great work! 
Cheers,
Henriko
