Shouldn't matter but I have these above (visually higher) the faction mods and HQ+. ex:

Why Not the Titans?
Since the HQ is a unit, it's not as simple as adding the production to it. I'd have to create a custom ability based on the regular infantry ability, which while not difficult, would require more testing to make sure it works and won't crash if you didn't install Reinforcements - Collegia Titanica.
If that condition is satisfied, I'll update it here. Otherwise, it'll go into a separate mod (if I even make it since I don't even play much Gladius nowadays .-.)
