Hello
When we are working on our team in order to improve our score it is normal we do not save every step, sometimes it works better sometimes not and we revert. In the Shadow Contest bosses, once we save we are kicked out of the dungeon, and when going back in the team lineup is not there.
Please add a save your team feature once we save our score, or simply leave it like in other dungeons where our last team used remains there, like in Vortex, we can still go in and save our team lineup and gear changes.
Thanks
