Just finish the dungeon

It must be really disappointing that even the hidden content is gone, nya. As someone also chasing gems, I totally get how you feel... Cheer up, nya!

It's such a shame if the hidden part disappears too 😭 If you were planning to complete the hidden quest right after finishing the dungeon, it must have felt so hollow in an instant ㅠㅠ 😮💨

Do the hidden ones disappear too? I thought hidden ones disappear after a certain date... Maybe they disappeared because time passed?
