Unearthed has been removed from the pack. It did lots of stone worldgen and as such your world will be wrecked if you update to this version. I strongly advise against the update unless you want all the glorious back updates and don’t mind starting fresh.
Added some quests. Only one of them is relevant. The rest tell you why I haven’t added quests.
Worldgen so give it 12G to start for max memory, after that you can drop it to 8G. This goes for the server probably the singleplayer too. Hard to believe that pack is that big already.
Unearthed because the mod author can’t be arsed with updating the mod so it doesn’t break on later forge versions. Thus the warning and major version change.
