Until GatherMate2_Data gets updated, people might want to look at WoWGatheringNodes. It is a Gathermate2/Gatherer import db uses the latest WoWhead data. It also adds the ability to import data on object not currently supported by Gathermate2 like the Wyrmtongue treasures.
I don't think this thread needs to continue Nevcairiel has pushed an official update on July 21, 2018 for patch 8.0.1. In the update, he ran the auto-parser to pull data directly from Wowhead and WowDB.
