Hey

The game is functioning as intended.

If this is occurring on the client, I'd suggest uninstalling and reinstalling an earlier version to see if you'll receive a better result.

Here's the link ~ http://img.oasgames.com/upload/1468827100/NarutoOnline_en_2.3.0.7181_oas.exe

If you're using an older client, try the newest version through the main site.

Let me know if that helped.
