My own experience with the event was a lot less stressful than most others, I'd guess.

The only things I really cared about with this event were the limited card for hitting 100k EP and the movies along the way. Which I've gotten, so I'm satisfied. I actually never encountered the bug, since I wasn't farming for items and support points. We're probably never going to get a straight answer about that.

I'm a F2P player through and through, and plan to continue being a cheapskate for at least a little while longer. I'll consider changing my ways if DMM and/or Nutaku knock it off with the whale-hunting. Maybe.
