Hopefully Nexon catches this quick.

I don't know about you guys, but I'm still going to go about my day as I normally would.
If I sit around and do nothing and they don't rollback, I waste a day and lose out on quite a bit of money I could have made.
If I do my daily routine and they do rollback, I just lose a few hours of my time.

It's entirely possible for them to take care of this without rolling back, but if they do, I don't mind losing a few hours of my time over it.
