Yesterday when I was almost done playing I reset my attributes and then went and did a test run and then exited the game. When I did the reset I had about 19900 primordial affinity (I spent a good deal of time farming all of that and was planning to use it the next time I re-skill). Resetting attributes is obviously supposed to consume gold, not affinity. When I logged in this morning I noticed that my primordial affinity had been reduced to just over 6000. I'm not sure what exactly caused the reduction, however it had been fine right up until I did that reset, so my best guess is that the reset code is somehow bugged and ended up taking my affinity.
