Fix Project Zomboid Map Load Failures
The server could not load a map folder listed in Map=. Custom maps need their Workshop item installed, their Mod ID enabled, and their map folder placed before Muldraugh, KY.
When this is the problem
- The log says Failed to load map, map not found, or unknown map.
- The server worked before adding a custom map.
- Players spawn into missing terrain, black void, or a server that fails during world load.
Repair steps
- Confirm the map's Workshop ID is in WorkshopItems and the map mod ID is in Mods.
- Put custom map folders before Muldraugh, KY in the Map line.
- Keep vanilla fallback maps at the end of Map, not the beginning.
- Remove maps one at a time if multiple new maps were added together, then restart and recheck the log.
Prevent it next time
- Generate Map, Mods, and WorkshopItems together from the same collection.
- Add one map pack at a time and boot-test before adding the next one.
- Document the known-good Map order before changing a live save.
Check the fresh log
After changing the server, restart once and analyze the newest log tail. Do not keep debugging the old failed startup log after the config changes.
