As database.log is reporting, this
Code:
<UnitType>UNIT_KAIXA_CARTOGRAPHER</UnitType>
does not match to this
Code:
<Type>UNIT_KAIXAN_CARTOGRAPHER</Type>
and this
Code:
<UnitType>UNIT_KAIXA_COMANCHE_RIDERS</UnitType>
does not match to this
Code:
<Type>UNIT_KAIXAN_COMANCHE_RIDERS</Type>
And therefore these errors are reported in Database.log because no such unit exists as is being referenced in table <Civilization_UnitClassOverrides>:
Code:
[9537.906] Invalid Reference on Civilization_UnitClassOverrides.UnitType - "UNIT_KAIXA_CARTOGRAPHER" does not exist in Units
[9537.906] Invalid Reference on Civilization_UnitClassOverrides.UnitType - "UNIT_KAIXA_COMANCHE_RIDERS" does not exist in Units
Additionally, the bulk of your text from Database log is because of this:
Code:
<Traits>
<Row>
<Type>TRAIT_GREAT_EXPANSE</Type>
The game already has a trait defined as TRAIT_GREAT_EXPANSE so you cannot attempt to add another trait with the same designation
