Doctrine MappingException with message 'The target-entity Entity\\ItemsBags cannot be found in 'Entity\\Players#itemsBag'

Доброго времени суток. Бьюсь уже второй день и не могу понять в чём дело... В рантайме ловлю ошибку:

PHP Fatal error: Uncaught exception 'Doctrine\ORM\Mapping\MappingException' with message 'The target-entity Entity\ItemsBags cannot be found in 'Entity\Players#itemsBag'.' in /var/www/vendor/doctrine/orm/lib/Doctrine/ORM/Mapping/MappingException.php:762 Stack trace: #0./var/www/vendor/doctrine/orm/lib/Doctrine/ORM/Mapping/ClassMetadataInfo.php(1028): Doctrine\ORM\Mapping\MappingException::invalidTargetEntityClass('Entity\\ItemsBag...', 'Entity\\Players', 'itemsBag') #1./var/www/vendor/doctrine/orm/lib/Doctrine/ORM/Mapping/ClassMetadataFactory.php(272): Doctrine\ORM\Mapping\ClassMetadataInfo->validateAssociations() #2./var/www/vendor/doctrine/orm/lib/Doctrine/ORM/Mapping/ClassMetadataFactory.php(251): Doctrine\ORM\Mapping\ClassMetadataFactory->validateRuntimeMetadata(Object(Doctrine\ORM\Mapping\ClassMetadata), NULL) #3./var/www/vendor/doctrine/common/lib/Doctrine/Common/Persistence/Mapping/AbstractClassMetadataFactory.php(332): Doctrine\ORM\Mapping\ClassMetadataFactory->doLoadM in /var/www/vendor/doctrine/orm/lib/Doctrine/ORM/Mapping/MappingException.php on line 762

При проверке доктрины, и апдейте, всё проходит успешно:

 root@comp:# php vendor/bin/doctrine orm:schema:update --force
 Updating database schema...
 Database schema updated successfully! "4" queries were executed

root@comp:# php vendor/bin/doctrine orm:validate-schema
[Mapping]  OK - The mapping files are correct.
[Database] OK - The database schema is in sync with the mapping files.

Пробовал очищать кеш, удалять прокси и перегенерировать их, но ничего не дало результатов...

    private $player;

}

Подскажите пожалуйста, что не так я делаю?
