September 8: in-game Wurmpedia errors

Platforms: PCUpdated Evidence checked

The same update addresses a CefWrapper load error when opening in-game Wurmpedia and its failure to open when Wurm runs with elevated Windows permissions. The notes describe those client changes. They do not instruct players to download a replacement browser library from an unofficial server. [1]

Officially acknowledged

September 8: an item removed during dragging could crash

Platforms: PCUpdated Evidence checked

The September 8 notes say removing an item from inventory while it was being dragged should no longer crash the client. Keep the action sequence in a bug report: an inventory item disappearing during a drag is the documented trigger, rather than every inventory or trading action. [1]

Resolved

September 8: performance drops caused by night shadows

Platforms: PCUpdated Evidence checked

The September client changelog fixes massive performance drops when all moons were below the horizon and nighttime shadows were rendered. This is a specific rendering condition. A slow frame rate at another time or with a different cause is not automatically covered by that resolution. [1]

Documented workaround

Deed rules and upkeep are managed at the token

Platforms: PCUpdated Evidence checked

The settlement token provides the deed’s rules and settings. Its Info entry displays deed size, guard count and remaining upkeep, while Manage windows changes village permissions. [4]

Documented workaround

Settlement founding is blocked by the chosen tile

Platforms: PCUpdated Evidence checked

A settlement token cannot be inside a cave, a house, or a submerged tile. Aggressive animals on the planned deed also prevent founding; animals in the future perimeter do not count toward this check. These are documented founding restrictions. [3]

Officially acknowledged

Client continued running after shutdown or a crash

Platforms: PCUpdated Evidence checked

The August 25 client changelog says the client should no longer remain running after regular shutdown or a crash. It also replaces the web-rendering library used for in-game Wurmpedia and says its CEF process should close when the client shuts down. [2]
