This wouldn't technically be an exploit. I know the line is fuzzy, but this was an error in the code that resulted from an oversight on our part. We can't/won't be policing and penalizing players for making use of this oversight if they choose to. In fact, this particular bug is so easy to reproduce that many players may be making use of it without even knowing they are doing so.
And I'm not really encouraging it. I just know that we don't have the resources or justification to hold players accountable for making use of this bug while it remains live.
