Tip if youre getting the exception, rename you mods folder to _mods to unload it (putting _ in front of a file will not load it remember for later!) Then see if the game starts. If it does, you have an issue in your mods folder. Go through your recently installed files (usually, the dlcpacks are the culprits) and rename them, adding a _ to the front of them. Keep starting the game, renaming 1 file to _ and then trying again. This can also be done backwards, renaming multiple files with the underscore and then working through. Keep loading and removing underscores until you start the game and it crashes. Whatever you removed it from is causing a crash, either from conflict or corruption. Look in that folder for anything thats messed up like car files etc. If nothing prevails, or you cannot be bothered, the easiest option is to delete whatever is causing the crash. All recently downloaded / modified files are renamed with an underscore to prevent them from loading. Underscores are gradually removed and tested to figure out the culprit In this scenario, the last one standing (mpclothespatch) is the one causing the crash. If you get a crash after removing an underscore, that means whichever you removed it from caused the crash.
Great mod! Just a fair warning to anyone installing this mod, at the moment the set times are a bit unrealistic (too short, in my opinion, could be a conflict though). Once you've first started the plugin, edit them to your choosing to make it a bit more realistic.
