I paid the primordial affinity cost to reset the passive tree but right when I hit the reset button the game disconnects me to offline mode. When I come back online, I find that my affinity has been consumed but the passive tree hasn't been reset.

Well, it's better than losing a character in offline mode, but it always sucks losing something after working hard to get it =/
Sigh ... I am still somewhat enjoying the game so far even with all these bugs. I hope the devs can somehow turn this buggy mess around with some consistent patching.
