Troubleshooter: Abandoned Children

[Notice] Temporary disability of development work

Hello everyone, this is the Troubleshooter development team.

Since yesterday, there has been a record downpour in Seoul, Korea.

As a result, the basement of the building where the development team is located has been flooded and the building has been blacked out since yesterday evening.

The building management office is working on electricity recovery, but it's a difficult situation to solve in a day or two.

Although the development team has switched to telecommuting, it can be difficult to respond quickly to some tasks.

We ask for your understanding, and we will quickly return as soon as the development environment is normalized and prepare for the next update.

Thank you.
