+# Unexpected Records
+
+Especially in the early days of a new game, you might see Spriggit refuse to serialize a mod with the verbage of "unexpected records".
+
+This is intentional as a safety mechanism to help avoid data loss.   If Spriggit encounters a record that it is unsure of, it refuses to proceed, rather than skip the record.
+
+## Solution
+
+Running into this error usually means that Spriggit's definitions need to be updated.  You can report unexpected records to the [Spriggit](https://github.com/Mutagen-Modding/Spriggit/issues) or [Mutagen](https://github.com/Mutagen-Modding/Mutagen/issues) Github issues.
+
+Please include as much detail as you can in the report, including:
+
+- The subrecord in question that it complained about (usually printed in the logs or console)
+- Information about what tools went into making the mod.  Did you just use the official CK?  Or did you use other 3rd party tools?
+- The source file (if you're willing to give it)
+
+With that info, Spriggit's definitions should hopefully get updated quickly in a new published version, and you'll be on your way.  The mechanisms are meant to be upgraded frequently in this way.
+
+Feel free to stop by the Discord to chat more directly!
