Brief bug summary: Although I have obtained all 12 keys during the Afterlands quest and I have unlocked all 12 locks, the quest is not prompted to finish.
More details: When I first began the Afterland questline, the background was pitch black however the environment was still the same. When I entered the Land of Warriors and the night fell, only half of the screen turned into nighttime. This may have just indicated that somehow the screen became off-center however I thought it would be logical to include any other minor errors included which may have lead to this major error. Also, during the Afterlands questline right before I began the quest to get the bag of treasure in the Land of Riches, I disconnected and was forced to reopen maplestory. After this disconnection, I obtained the next key and noticed that it prompted me as if I had only obtain 1 key so far (1/12 keys obtained). I hoped that this would have no major effect on finishing the questline so I decided to continue on until I obtained all the keys although the game only recognized that I had obtained 3 keys. Once I got to the door and used my keys on the remaining locks, there was no prompt or cutscene to finish the Afterlands questline.
I attempted to log out and log back and upon reentry I was greeted with the reappearance of all 12 locks. Even the locks I had opened after disconnection also reappeared. However, you can clearly see that both the texture for the lock being opened and the lock being closed are overlapping each other.
For a solution to this issue, Ashkaya could be given the option to give any keys that were somehow lost during gameplay according to the quests the player has finished. Ashkaya could check the quests the player has done and if the player had already completed the quests needed to obtain each key, Ashkaya could give these keys back to the player.
