Hi,

The Bencoding specification (Link removed by Mod - it wasn't working ) stipulates that dictionaries should be encoded in key lexical order; however when creating a simple torrent consisting of a single file and a single web seed URL, the “url-list” key appears first, before e.g. the “created by” key. This causes some torrent clients to fail to parse the resulting file (https://github.com/alanmcgovern/monotorrent/issues/332  ).

very intersting

This has been fixed for version 2.78.  There was a minor problem with key ordering when saving .torrent files.  Everything should work well now.
