Hello again, I think i might have found what I think happened to you on my provie, I hit the tool buttons and nothing happened.
This was because AutoConsume was on. The Tools buttons only work if the items need to be cast.
If you want to do it manually look in your maintained spell effects right click and cancel the tools. The buttons will then work. if you have auto consume on they don't, but then again if you have auto consume on you wont need to use the buttons anyway lol. The only time i find the game cancels my auto consume on harvest tools is when I use my AA mirror and change spec, however I know that this is not the case for everyone.
I have no idea why it did it :/ but that seems to be the reason the buttons do nothing
