Topic info records need to have specific order defined via mNext and mPrev fields (next and previous records). When loading multiple files a record may be inserted into middle of the topic but neighborhood records may not be aware of it. Having the order it's possible to move the records within one topic. Sort the record once after loading all content files but preserve the order for all other operations. Use std::map to group info ids by topic to make sure the topics order is stable. Keep order within a topic for info ids on loading new records. Use this order later for sorting the records.
