Are new dungeons supposed to unlock automatically? Did I progress too fast and miss the scene that starts unlocking dungeons? Just finished the 300,000 repayment and was given the task for the 800,000 repayment but still only have access to the beginner dungeon that only has 6 floors...Also don't appear to be any new scenes available.
After each repayment the game checks several variables to advance the story:
1. If the previous dungeon has been cleared completely
2. Grace's development status [Idea of Chastity] or Chastity concept etc in game has to be below a specific value
3. and ofc if the repayment has been successfully done
If those are successful, an automatic event should start after entering the inside of the Inn that starts the renovation of the Inn and automatically unlocks the next dungeon.
E.g. after the first repayment you should get an event where Grace gets invited to a banquet/celebration. In the course of that
the game sets the flag to unlock the next dungeon, the tidal dungeon.
Most likely you havent done all the H-Events available to you in the first stage. You can go to the recollection room and have a look which events in the first stage have not been unlocked and go do them. After that the story should advance.
