Hey Guys, I just upgraded to Ubuntu 13.10 a few days ago and im getting a bizzare error after just installing Mono-complete and trying to run the server. skay@ks3329890:~/ksp$ sudo mono KMPServer.exe [sudo] password for skay: Missing method System.Linq.Enumerable::Where<[1]>(IEnumerable`1<!!0>,Func`2<!!0, bool>) in assembly /home/skay/ksp/System.Core.dll, referenced in assembly /home/skay/ksp/KMPServer.exe Unhandled Exception: System.MissingMethodException: Method not found: 'System.Linq.Enumerable.Where'. [ERROR] FATAL UNHANDLED EXCEPTION: System.MissingMethodException: Method not found: 'System.Linq.Enumerable.Where'. Any Ideas?
