Improved Vivox implementation and overall chat functionality.
Fixed items that are no longer in your Steam Inventory being displayed in the in-game inventory.
Fixed some missing pop up windows.
Added: Three new blessings that add 4 damage modifiers against each armour.
Added: Blessing of the Hunter: deals more damage against \[Beasts].
Added: In NGP+, tribes now sometimes receive one or two altar creatures to fight on their side.
Changed: Distribution of land events (POI) is now more randomised. Before, you would have very little chance of seeing the new POIs. To increase the chance even more, POIs are now all unique.
Changed: Increased the chance of events during expeditions.
Changed: The option "Add to existing group" is now above "Add to a new group".
Fixed: Some trait parameters were missing from expedition log, giving localisation errors.
Fixed: Some events would allow you to see past unconquered Outposts.
New skill: Increase storage capacity
New “?” symbol in the menu to send merchants to resource carts
The last version used for saving is now also stored, so warnings can be shown when necessary
When canceling skills, it is now checked whether subsequent skills would still be unlockable without the canceled one; only if that is not the case are those also canceled
You can now see which resources merchants and armies are carrying

The Undead Lord always started with 20 flying skulls, which he would automatically send along
The X buttons in various UI elements were sometimes overlapped by other UI, so they could only be clicked at the top-right corner
The “send back” button in the overworld was also activated even when the unit was already on its way back
The number of peasants spawned per skill point has been reduced to 1
