After a very long break I recently started to play ES again. Since I don't like how the heroes are not assigned faction-specific, I began to edit my save games (first turn, new game) to change the starting heroes for my games following the instructions here:

https://www.games2gether.com/endless-space/forum/37-modding/thread/15797-changing-starting-heroes

For my modding purposes I made myself a list with all heroes and their specific ID numbers through testing and with the help of the ES wiki. I understand that there should be a total pool of 82 heroes in each game, with Tarosh Emlek being the last and final addition (ID 82, Endless Day Hero).

But I noticed that in all of my save games the following heroes are non-existent and can also not be added by editing the files:

Mani Dar-Omnis  (Automatons; presumably ID 74)

Lucrum Yoku        (Dust Collective; presumably ID 75)

CUSO4 Ponders   (Harmony; presumably ID 76)

Enil-Nex 8043      (Virus; presumably ID 77)

All of these were announced for the Disharmony Expansion:

https://www.games2gether.com/endless-space/blog/350-disharmony-new-heroes-part-2

The only Disharmony hero which seems to be functional in all cases is Serena Tora (ID 78).

So my questions are:

Where all of the announced Disharmony heroes ever included in the game?

If yes, where they later removed by purpose or is this a bug introduced by later patches? Could this be fixed?

I have validated that there is indeed a bug in the latest and last release 1.1.58. While the hero descriptions for the IDs 74-77 are still present in the Localization_xp1_Locales.xml file, the corresponding IDs are missing in the hero.xml of the Disharmony expansion. I fixed this by importing the missing data from an earlier hero.xml (Disharmony v1.1.0). The fix can be downloaded here:

Since this is an unofficial fix, I posted it in the modding section.
