Hi Everyone! We've just applied a patch to the game that will improve grouping mechanics - specifically players using the "join" feature where the dungeons would not start should now be able to enter dungeons. We are also working on another major patch that will include further optimizations, dungeon modifications, and bug fixes. That patch should be available by tomorrow. Please continue sending us feedback in-game. It is helping us quickly prioritize fixes. Thanks for all the support and encouragement!
