Auto Extracted Files
Certain Minecraft mods have auto extracted files that are created whenever you run your modpack. At this time, these files should be removed from your modpack before exporting from Twitch App.
To do this, right click on your modpack profile and click open folder. Navigate to the "mods" folder and delete the "memory_repo" folder.
That's it! Be sure to export your profile before launching it again, otherwise you will need to do this again.
This will prevent multiple extracted files and versions of the history of your modpack.
