In classic wotlk i am trying to exchange emblem of heroism for valor at the vendor and nothing happens. I turned off all addons and still I click away and nothing happens.
I have 21 of valor and 22 of heroism so there is no reason it shouldn’t let me exchange.
Is this a bug?
I’m having the same issue trying to exchange Emblems of Valor for Emblems of Heroism. The initial trade box pops up, but when I click on any of the emblems the trade confirmation dialog box does not appear. I also reset my interface and entered the "/console cvar_default with no luck.
