i cant search dregora in curseforge, neither in app nor FTB app. Also since curseforge is turning unfriendly towards 3rd party minecraft launcher, i suggest hosting Dregora in other place such as modrinth and AT launcher

What 3rd party launcher are you using if I may ask?

Good point, I've just checked though and had already turned it on @SamB440

Potentially Dregora has third party download requests turned off in its CurseForge settings @NLBlackEagle. Otherwise unsure why it would not appear.
