Not all outfit/character swaps have been tested. If the game doesn't load or Aloy looks the same the swap didn't work.

If the game won't load try the following:

• Use the Clear Cache button in the Settings tab. Restart the app. Reinstall the mod using Install Pack
• If that doesn't work, use the Delete Pack from the Settings tab. Reinstall the mod using Install Pack
• If that doesn't work, try deleting the patch file. The patch is placed in %GameDir%\Packed_DX12\Patch_AloysAdjustments.bin.

If the app won't load or is giving errors during loading:

• Use the Clear Cache button in the Settings tab. Restart the app. Reinstall the mod using Install Pack
• If that doesn't work, try deleting the patch file. The patch is placed in %GameDir%\Packed_DX12\Patch_AloysAdjustments.bin.

If you change the bin file name or move it, be sure to update config.json with the new name, otherwise the program can't get the original game files.
