After moving my WoW install to a new drive, I updated both the ‘Default Install Directory’ and ‘Folder Used For Game Play’ settings on the desktop launcher. Every time I restart the launcher the ‘Folder Used For Game Play’ setting reverts to it’s old value.
Updated from ‘D:\World of Warcraft’ to ‘F:\World of Warcraft’ moving from a hdd to an m.2 ssd.
