Updated Localisation
Hello everyone,
We have a hotfix out that could prevent some players from activating the DLC in game. Please update your game files to the latest version.
Patch notes:
Fixed a crash on load of some older saves.
Fixed an issue with the in-game DLC selection that could show the DLC as enabled when it was not.
We've just released a small hotfix to address an issue that could prevent resource transportation in certain situations.
- Fixed: Moving a production building or storage building could prevent transporters and production workers from collecting resources from that production building.
We've just released Patch 1.11.0.18, which addresses the missing grass and cliff textures reported by some players using AMD XT graphics cards. This workaround should resolve the issue for affected players.
Changelog
- Adjusted texture buffer object binding to work around a recent AMD OpenGL driver issue.

Full changelog:
Gameplay
- Fixed: Aspirations could be completed without fulfilling all required "sub-quests."

- Fixed: The Bailiff was not gaining experience.
- Fixed: Workplaces could occasionally produce goods without consuming resources if a worker brought resources while others were already waiting for work.

- Fixed: Tier 3 Houses were being built even without the required paved roads.
- Fixed: Tier 3 Houses would not downgrade back to Tier 1 if patrol coverage was removed and Tier 2 requirements were not met.
Buildings & Construction
- Fixed: Deleting a gate snapped to a wall, whether built or in preview, would leave a hole where the gate was removed.
- Fixed: Monument sub-buildings that allowed multiple parts, such as a dorm, could have their function switched to single-part buildings, such as the Apiary and vice versa.
- Fixed: Monument decorations now appear immediately upon unlocking while editing a Monument, without needing to select another building.

- Fixed: Attach nodes remained visible after a part was built under specific circumstances.

UI / UX
- Fixed: Interactive buttons on the Map Generation screen were unreachable on lower screen resolutions.
