Why the Secret Spell Scroll system would have never worked.

The public one only works once per SC, and at a low percentage at that as far as I know.
I think the scania crashes might have something to do with this.
I'm expecting Nexon to make SSS untradeable to the NPC in a SC/patch soon, screwing over everyone who bought them, as it was never an intended feature for them to be used as currency anyways.

It works every time the server crashes or there's a SC. Which lately has been very frequently. This has also been private for well over a month now at the very least. Unless Nexon does something immediately, it's going to get much worse in the next day or two. Worse as in 1k for 100 scrolls.
