Harvest has been added to the core game and has been vastly reworked. It no longer contains a garden-building component, nor a permanent garden of your own. Instead, you now have a chance to discover a portal to an established Sacred Grove in maps, which contains several different harvestable plots.
Harvest characters will soon be migrated to their respective parent leagues. The Sacred Grove and its contents have been removed. Harvest Infrastructure and Seeds outside of The Sacred Grove will be removed at a later date.
