December version introduces a new ironman mode "Surrounded by Traitors" which makes maintaining loyalty of imperial officials much more tricky. Especially over time since the loyalty degrades more when time passes when this ironman mode is selected. This version also introduces a new event related to loyalty and interface improvements.

- [feature] Ironman mode: Surrounded by Traitors. Every 100 turns starting Loyalty of new imperial officials (courtiers, governors, officers) is reduced by -1 (up to -5), except political officers who are unaffected. Much higher chance for "Loyalty decreased" event. "Loyalty increased" event will never happen.
- [feature] New very rare event "Loyalty decreased". Each imperial official has 50% chance for Loyalty -1. Note that this event is much more frequent if Surrounded by Traitors ironmode is selected.

- [interface] Summary of governors/courtiers/officers on Empire/Summary screen now also displays average competence/loyalty/corruption.
- [interface] Additional accessories for imperial officials portraits (more earrings for females and a new data visor for males). Note that with old saves you might have some existing portraits changed and might see some odd overrepresentation of certain accessories, it's just a cosmetic thing and affects old saves only.
- [interface] Increased chance for accessories for female portraits.
- [interface] Reverted back to the old faction icons (while the new ones were more sharp and visible, I have to agree with some concerns raised on the forum that the old more blurry ones are more consistent with the style of portraits and since factions icons are displayed mostly on portraits making them look good with portraits is a priority, plus the imperial eagle which is displayed on governors portrait is a blurred one, so I suppose it's more consistent to make all over portrait icons with blurred versions).
