Do you want to know why it doesn't get updated?
The dev of the mod (FlatOut) decided to put a virus code that targets people that he doesn't like by using their SteamID and messes up their game. Basically the virus ****s up the save game so the player's in-game house burns down when they try to play the game. This only happens if you are on his blacklist, other users don't get the virus. He wanted to target youtubers (I don't know what he has against youtube video creators, but I guess he hates them all). He added my name and SteamID to the blacklist too, because I blew the whistle on his virus.
The dev of the mod-loader put in an antivirus on update 0.4.7a. Well, the dustman mod only works on 0.4.7 (no "a") because the virus code got detected and the mod got disabled. Mod-loader 0.4.7 doesn't work anymore on the updated version of My Summer Car so the virus filled dustman mod doesn't work either.
The thing is, if the mod gets updated, I wouldn't doubt if he adds a virus that corrupts the operating system as a method of "retaliation" because I blew the whistle on him so it not getting updated is actually a good thing.
