Greetings.
I suspect my account has been stolen, because I am absolutely sure I didn’t change my password and I can’t login now. Last time I logged in was yesterday.
I also tried to request a temporary password but the system does not find any email I could’ve used.
Sorry to hear that. 
However I think I can help you to find your account. Could you please confirm that you want to find the password for my.sasaki mudfish account?
If then voidmochi_at_gmail.com email address is one registered. Please check the inbox or spam box on your gmail account.
Hello, thank you for the reply.
The problem was with another account.
Today I received a bunch of emails with temporary password. I managed to log in and already changed the password for ensurance. So I suppose the problem is solved even though I have no idea why I couldn’t log in that day.
Thank you very much.
Cool! 
I hope now everything goes well with mudfish. Please let me know if there are any other problems.
