Hello Aternos Team,
Can you please add the modpack "StoneBlock"?

StoneBlock is a modpack similar to a skyblock modpack, but it is underground. It has 56,790 downloads o the twitch launcher, so I think it definitly falls in as a reasonably popular modpack. It is for minecraft 1.12.2. It features quite a few popular mods. I could not find a mod list for it online.
