以下兩個檢查看看，關閉之後，開啟新城市，如果錯誤內容有變化，就表示找到原因

IPT - Improved Public Transport 3.8.0
http://steamcommunity.com/sharedfiles/filedetails/?id=424106600

Transport Lines Manager 5.0.2
http://steamcommunity.com/sharedfiles/filedetails/?id=408875519

另外請去Steam安裝資料夾內，即SteamLibrary\steamapps\workshop\content\255710
搜尋字串「ImprovedPublicTransport、TransportManager、SimulationManager」

檔案所在的資料夾號碼，就是有問題的模組號碼，例如「424106600」
再把它前面加入「http://steamcommunity.com/sharedfiles/filedetails/?id=」

這一串網址就是有衝突的模組的訂閱網頁，點去把它取消訂閱吧
另外不要想用關鍵字去工作坊找，幾乎不可能找的到...
