https://www.pathofexile.com/forum/view-thread/2237779/page/1This time around we won't be running a Flashback (or similar) event for the last month of the league. Player retention during Delve has been excellent, and due to the infinite nature of the mine, we'd like players to be able to continue their progress in the existing league without having to weigh up whether or not they'd prefer to swap to an alternate event in parallel.
Having said that, we are working on something small that is separate to existing/future leagues and we may be able to talk about it soon.
