I bought the game to play with a friend. Every time he tries to join me or vice versa, the game declares that he has mods (even though he does not ). We tried troubleshooting it for hours. Finally, he uninstalled and reinstalled the game, and it worked; no mods were detected. The very next time he opened his PC, it again declared that he had a mod, and he could not join me. This entire ordeal has been awful. Hopefully, my suggestion is a system that tells what it detects as a mod, or even better, a better system to detect what a mod is in general. Because, as it stands, I cannot play this game with my friend, which was the primary reason I bought it. I really hope you can implement a system like that. I don't want to refund this game, but if I can't play the game with my friends, then it kinda defeats the purpose for me. 
Thank you for your time.
