Since the server maintenance performed earlier today, I find myself unable to mine copper in Elwynn Forest.
I've done a complete circuit of the zone a couple of times and find very few nodes that appear on my minimap. Whenever I draw near to these nodes, they simply disappear. I've asked in general chat and it appears that I am not the only one having this problem. A quick check into Westfall indicates that the nodes seem to be working there.
I am reporting this issue here as I also seem to be having trouble accessing the bug tracker system. Perhaps somebody who can access the bug tracker could check to see if this problem is being addressed and if not, please report it.
