A hotfix is now live for THREE KINGDOMS.
This means that in saves started before release of The Furious Wild, rebellions in regions that are now Nanman will no longer cause crashes, but the rebel armies that are spawned will look weird. For example, they might have missing character art or missing unit cards.
We encourage everyone to start a new campaign to get the full benefits of the changes the release of The Furious Wild has brought to the game.
