1. Wizard class bug: Arcane Torrent skill with Arcane Mines rune active
If after placing some mines cast Hydra skill - mines will disappear.
2. Achievements: not counted properly
I have plenty achievements that are not marked as done. I.e. finishing act4 by wizard achievement (i play at nightmare as a wizard now). Or reach level 5 blacksmith (my BS level is higher than 5). Plenty of them.
