Noticed this a little while ago, but when I try to use the honorbuddy launcher to open WoW and HB, the window closes, Honorbuddy starts up, but no WoW.
After the patch you need to update wow manually and login once to agree to the EULA. Afterwards it should work again. Please also read: https://www.thebuddyforum.com/honor...-update-status-patch-6-1-2-build-19802-a.html
