Worker Skill mechanics, including what factors contribute to a character being able train workers skills (and to what levels), are now part of the Encyclopedia.
Additional culture and character traits now impact Worker Skill training mechanics. For example, characters of a culture with the Geomancy trait have +2 max Prospecting skill level teachable.
Worker roles are now properly tracked for Outposts upgrading to a City or Fortress. This allows adding workers after the fact to the specific roles (as per the initial project window). An action for each valid role is shown (e.g. 'Add Builders', 'Add Settlers', 'Add Pioneers').
Independent Realm AI now considers estimated siege duration when deciding whether to sally forth against a siege. They are now much less likely to sally early and much more likely to sally when an assault is imminent.
Cancelling a Nomad Camp upgrade before progressing the turn will now refund the cost.
Fixed Nomad Camp upgrade cost not causing a UI refresh (and the cost thus not being visibly deducting until something else causes a refresh).
Fixed a bug causing Nomad Camp upgrades to finishing construction instantly. They now take the indicated time to construct.
Fixed a bug where Nomad Camp 'cancel upgrade' instead built a new upgrade. This made it possible to duplicate upgrades.
Fixed a bug where Nomad Camp upgrades would provide most benefits even when not built yet, or when superseded by a higher-tier upgrade.
