1st bug.
First and most important bug of all is not even a game's bug but a bug of the website itself.
I have created my account using my Outlook email but it seems the system itself is not working properly as it doesn't send me any activation email, though at least i can still play so that's not much of a problem.
2st bug.
I cant delete any of my characters.
This may come from the fact i cant activate my email account so i cant get my deletion password.
I've tried using my main password, nothing, then I tried 123456789, 1234567890 and 0123456789.
None of these worked to delete my character.
3rd bug.
This is a bugged quest that's impossible to complete.
Its name is ""Secret Tattered Papers" and you get it from the item "Bundle of papers", an item you gain from completing another quest.
its objective is to bring this item to Teacher Kiki in Kokkara village but even going to him does nothing and if you log out and back in, the messages "Trigger error in progress." and "Failed: Secret tattered paper." will appear.
The only solution is forfeiting the quest and either leave the item in the bank or throw it away.
