Migration in Progress: We are currently migrating the Hub to read-only mode as we transition to our new platform, The Forge. During this process, you may experience intermittent access or limited functionality on the Hub. Once complete, all new activity should take place on The Forge. We appreciate your patience while we complete this migration and look forward to seeing you at forge.sp-tarkov.com.
  • Cause: Moving the live EFT folder somewhere other than where the BSG launcher installed it
    • Resolution: Move EFT back to the original install location
  • Cause: Copying EFT from another computer without installing it
    • Resolution: Use the EFT launcher and install the game normally

This issue can almost always be fixed by uninstalling SPT + live EFT and installing again
