I created a sequence named TANK. I then got an error in BugSack for a GSE/API/Storage.lua.
I deleted the TANK macro, and the error went away. I then went to create a new TANK macro and it give me the “Sequence Name TANK is in use. Please choose a different name.” message.
So I then closed WoW, deleted all GSE from my Classic WoW install. Reinstalled the addon and started WoW.
But short hand if you do a /run GSE.Print(_G['TANK']) in-game, something is creating the _G[‘TANK’] object. As it exists GSE won’t try to create a macro object of the same name as if two mods are trying to access and update it anything could happen. _G stands for Global Variables which means that every mod and WoW itself is able to access and change these objects. The things that exist in this space range from the specific to the very generic.
