There is a known issue occurring in Secret Passages at the moment with the quest "A Peaceful Warrior" which asks players to visit the Dojo. We have recently released a fix that prevents any further players from encountering this issue. The team is now working on clearing up the quest from other players' games. However, this should not block you from any other game features, and the Dojo will eventually appear in a few weeks, allowing for completion of the quest.
