Hello,
I’d like to share some details regarding the severe lag some users have experienced due to increased communication load in the Odyssey areas, particularly in Sheol: Gaol.
After investigating these occurrences, we found that the communication load between Sheol: Gaol and the servers is higher than those of other content. Our results allowed us to track down the cause to some extent, so we’ll proceed with further examination and come up with a countermeasure to help reduce the load. This countermeasure is planned for implementation in the March version update.
We are still looking into cases of players being unable to access Sheol: Gaol in the first place, but it’s possible that the countermeasure may help alleviate this issue. If you are still experiencing these symptoms, we’d like to ask you to
submit a bug report so we can further investigate.
We sincerely apologize for the inconvenience and frustration these issues have caused.
