For debugging, the log file is your friend. Start up Factorio, then look for factorio-current.log in your application directory, open it, and search for Checksum for core
. The following lines will show you in which order your mods have been loaded.
In the mod settings of my mod, there's a start-up setting "Write debugging output to log file". If you turn that on, the mod will leave a breadcrumb trail in your log file, making it possible to see where in the code it gets stuck. (Be sure to turn the setting off again when you're done, or your log file will be spammed with lots of data.)
About providing saved games: you'll find them in the saves
folder of your Application directory (see the link above). If you upload a saved game, I can synchronize mods and settings on loading it. You could try to send me a private message with the save as attachment on the forum, or you could upload it to Dropbox or whatever and link to it here. (Please note that I have no account at Google, Dropbox etc., so you should make sure that the link is public or else I won't be able to download the file.)
