Version 2.5.00-PR1 (Experimental):
This update provides experimental support for the closed-beta for the upcoming underground expansion. As far as I can tell, all features are functioning, but there may be interactions from new game content that are not yet accounted for or properly handled.

The following change-log applies only when suing the closed-beta branch of the game:
- Updated civil war logic to prevent crashes when sorting camps by specialism.
- New orc camp specialism (specialism 6), has been introduced; Orc Mines.
- - Despite having only 1 function (to allow orcs to move underground), hosting no army, and having no special features, this still counts as a specialised camp for purposes of building Great Halls, choosing a new capital, performing challenges, and so on.

Version 2.4.05 (Dockyard Brawler Improvement):
- Improved target acquisition rules for Dockyard Brawler minion trait when the minion is held by an agent of a good society.

Version 2.4.04 (Great Construction Fix):
- The Great Construction property no longer succeeds in specialising a camp if it runs out of money, and falls to 0.

Version 2.4.03 (Fixes):
- The Raid Outpost challenge in orc camps will now consider intolerance, and ignore those that they are totally tolerant of.
- - When a player agent uses this challenge, it will always target outposts of societies that are not dark, even if the orc camp belongs to an orc culture with intolerance +2.
- The Dockyard Brawler minion trait will no longer disrupt those who are lying low.
- The Dockyard Brawler minion trait will not disrupt player agents if the agent with the minion with the Dockyard Brawler trait is a player agent themselves or belongs to a dark society.

Version 2.4.02 (Hotfix):
