I am tired of not being able to play the game due to so many people abusing crashes and mods in multiplayer, that I am releasing my own private mod based on XL Trainer.
The main features of it are its "private" crashes that I "invented", and I am fairly certain that you can't protect yourself from them.
The source code is also available to download, there's a link in the readme.
Everything required to use this mod is inside the zip file.
