WowAce

Toggling minmpa/world map icons are not working currently in TBC Classic. I used import to import data, not selecting TBC and cannot see classic herbs.

This fixed the problem, credit to moonlit_vamp's Profile - Member List - CurseForge

Locate the following files in your addons\GatherMate2 folder:

     Collector.lua

     Config.lua

     Display.lua

     GatherMate2.lua

In each of those files, there is a line a few lines from the top that reads:

local WoWClassic = (WOW_PROJECT_ID == WOW_PROJECT_CLASSIC)

Change it so that it reads:

local WoWClassic = (WOW_PROJECT_ID == WOW_PROJECT_BURNING_CRUSADE_CLASSIC)

Tried the above but those lines do not even exist in my Display.lua nor Gathermate2.lua

Changed them in the other two files but the original problem remains.

However if I set the Show X nodes to "Always show" the nodes do appear, so it appears the issue is with Gathermate realizing I am tracking the nodes despite the fact that I am.
