Hello, this is Prettybusy.

The error has now been fixed with an emergency update. 

We sincerely apologize to all players who faced significant inconvenience over the past nine hours.

Also, we apologize once again on behalf of Tartaros for the insufficient hospitality

shown to players from various nations who came to celebrate Mammon’s birthday.

There was an error in the summoning UI in some versions. 

Like the login issue, this error has also been fixed.

We will take greater care in managing Hell to ensure no issues occur until the end of 

Mammon’s birthday celebration.

Thank you.
