The requirement to enable Debug privilege is a consequence of the changes introduced by Patch 5.18.
In Patch 5.18, the game installation process was changed. The game launcher modifies certain permissions in the game process, and in order to connect to the game correctly, Miqobot requires additional Debug privileges granted by Administrator account.
Depending on your Windows installation, different permissions may be required. Therefore Miqobot uses a combination of several solutions when connecting to the game.
