Default location is already listed on the MQ2Nav wiki, see
https://www.mmobugs.com/wiki/index.php/MQ2Nav
MQNext\MQ2Nav was the location from MQ2, it can be deleted.
MQNext\Resources\MQ2MeshManager is left over from an old plugin which was removed a few months ago, it can be deleted.
None of those locations are in a fresh zip. I don't think they would be created now.
