Hopefully Nexon catches this quick.

I really don't understand Nexon's reasoning for no rollback on this or the Phantom thing.

Let's do an analogy.
You live in a town where there was just a massive flood due to a dam breaking. You have a magical sorcerer in the town that has the ability to send everyone back in time and fix the dam before it breaks. Your town also has a single bucket, which could be used to remove the water from the town, one bucket-full at a time. The town decides to use the bucket.

Makes no sense to me.

Magic comes with a price, dearie.
