Holy s'it! I figured it out. The bug was because of the nation number, which made the server think that it was a different nation mod entirely. I tested it and was able to send out a pretender for Dwarfs fine.

However, I had to make a new .dm file in order to change the nation number. It is downloadable in this post.

Also it is possible that someone made a pretender based on the accidentally available Monolith and Alchemist made available by the dwarf mod. If someone has used a Master Alchemist or Monolith as a pretender, it's very recommendable to remake and resend the pretender.
