7. It's highly recommended to disable your antivirus or, otherwise, to add exceptions for Anomaly and GAMMA folders before starting. BitDefender will 100% crash the game randomly because it doesn't like MO2 Virtual File System.

8. Make 2 different folders at the root of your drives (C:/, D:/): one will contain GAMMA, and the other will contain Anomaly. Don't make these folders in Downloads, Program Files, Documents, Desktop. For instance use: C:/GAMMA and C:/Anomaly. Do not use special characters in any of the folders ([-, etc)
