5- Description:
I am trying to grind for Darkiron Ore for a Champion Chestguard. When I start the grind, either by clicking on the item in the plans window or from auto level up (either levels 40 or 41) the grind stops immediately and the report window pops up with zeros. I have 3 open slots in the inventory (not the bank).

6- Summary:
Can not grind for Darkiron Ore.

Never mind. Refreshed and now it is working.
