Rimworld Err Site Label Detected New //top\\ Jun 2026

The "ERR: [Site_Label] [detected]" error is a common issue in the popular colony simulation game, RimWorld. It primarily manifests as a broken quest in your journal, often with placeholder text like [Site_Label] or [detected] , making the quest unplayable.

This is the #1 culprit. When the Biotech or Anomaly DLCs were released, Ludeon Studios changed how Site spawning works. Mods that add custom factions (e.g., Empire , Vanilla Factions Expanded - Mechanoids ) or custom biomes ( Alpha Biomes , Regrowth ) sometimes hardcoded site labels. If a mod author used an old patch to generate sites, but forgot to update the label logic for the SitePartDef , the game throws this error because it finds the physical site (the map tiles) but cannot find the label for the "New" instance.

RimWorld handles texts, titles, and descriptions dynamically using placeholder strings in its XML architecture. When the storyteller triggers a map event (like a stash opportunity, camp raid, or ancient complex discovery), it pulls structural rules from a quest template. rimworld err site label detected new

Here is a systematic approach to eliminate this error, moving from simple to more involved solutions.

Prevention is better than cure. By following these best practices, you can significantly reduce the chances of encountering this and other issues:

If you are running multiple total-conversion world mods simultaneously, disable them one by one.
