As a level 11 tauren shaman i tried to learn "two-handed maces" at the weapon master in Thunder Bluff. It shows, but it's red coloured and i can't click "Train".
Mining used to work on this server, so this is a new thing:
Usually when i mine everything out of a copper vein, that vein comes back almost immediately in the same place, also it is unusable (I get the "invalid target" error message when i click on it). Only tested with copper veins so far.
I started a mage yesterday, and i had to stop, because you can't play the game like this. At least with casters. This bug wasn't always present, it came up sometime this year.
