Thank you for your feedback, I have been working for the last hours to fix these bugs. A new patch will be released in a matter of minutes to fix those issues, including the one about diplomatic missions.
The new features I added ended up converging with some core structures, but many of the issues will be fixed very soon, I have already corrected many of them and in a matter of 15 minutes or less the new corrections will be released!
Thank you for your comment and feedback!
