DayZ troubleshooting
Common DayZ types.xml errors
An item failing to spawn does not automatically mean its nominal value is too low. The complete Central Economy, mission tags, available locations, persistence and installed content all affect the result.
1. Malformed XML
A missing quote, closing tag, angle bracket or root element can prevent the file from parsing. Validate the complete document, not only the edited entry.
2. Duplicate classnames
Two <type> entries with the same name can create unpredictable results or make later edits difficult to reason about. Keep one intended entry per classname unless a documented workflow specifically requires otherwise.
3. Wrong classname or letter case
The classname must match the item defined by the game or installed mod. Display names and trader labels are not always the same as internal classnames.
4. Minimum greater than nominal
When min is above nominal, the economy targets conflict. Review both values and the intended server balance.
5. No suitable usage or value tags
An item may have valid XML but no suitable configured locations on the current map. Tags must correspond to the mission configuration and available spawn points.
6. Counting too many stored items
count_in_cargo, count_in_hoarder, count_in_map and count_in_player can affect how existing items count toward the target. Storage-heavy servers need deliberate flag choices.
7. Economy persistence and old items
Changing XML does not always instantly remove or replace everything already persisted. Testing after a backup, restart and controlled cleanup is safer than repeatedly changing values.
8. Mod mismatch
A types.xml entry cannot create a modded item if the server does not load the mod or the classname changed between mod versions.
9. Editing the wrong mission file
Hosts may keep separate mission folders or active profiles. Confirm the exact live mission path before uploading changes.
10. Over-editing at once
Large untracked changes make troubleshooting difficult. Use versioned backups and test smaller groups of edits.
Quick checks before uploading
- The XML document parses without syntax errors.
- Every edited type has a valid, exact classname.
- No unintended duplicate classnames exist.
- Numeric fields contain whole numbers where expected.
- Flags use
0or1. - Usage and value names exist in the current mission setup.
- A backup is ready before the server restart.
