I've been trying to set up a FTB Monster server for the last 2 days and since there are about 15 versions of it since 1.0.0 and each adds and removes some mods from the pack, figuring out which version is the Aternos server using is quite hard, have in mind that each version pack needs to be downloaded entirely and they are all above 120mb each.
I see you have the builds for AgrarianSkies, Lapitos Galacticraft and others, so how about adding that to the FTB packs in the mod list?
