They did however put out a part about no refunds in the case of cast changes. Which for a prerecorded event almost screams "there will be changes". Just like with Kotoka skipping a collab because of schedule change, when she is on a break with no date of return announced anyway.And just to play devils advocate they might be just holding off any other graduation/termination till after the AR Live because they are too fucking lazy to make another poster again.
