I don't actually know if the cause of this is the Ropalolyst mission itself. I'm just reporting it because it happened directly after that mission. I fought the Ropalolyst first time, we finished the mission and the game set me back to MR26 and prompted me to take the MR27 test over again. Was about to just repeat the test but decided to restart app first and the that worked to put me back to MR27. No biggy just reporting what happened to me.
