Steam Chainlink Couplers Broken On Most Freight Stock Main-spessart Bahn

I've taken a variety of screenshots from my freight jobs I've done with the BR204 Diesel Shunter and basically most of your freight stock have their chainlink couplers broken as in, they are not connecting to the other wagon because of an issue with that particular part of the object model. May of been some issues with the porting it over. Most affected freight cars are the Shimmins, the car transport and the Railton one with the white and red.
