Two bugs from the beta:
1) The druid grove always crashes during the boss fight after I hit him enough times. I've tried a couple times now, and each time it was looking like I was going to get a win, but around 20% health when I attacked the boss the game crashed.
2) The game keeps telling me there are new puzzles available, but when I click on the explorer guild, there are no new puzzles. Aside from the druid grove and the vicious dungeons, I've completed every dungeon and available quest, so I'd expect to have most of the puzzles unlocked by now.
