Hey, I haven't seen a thread related to this, so who knows, but has anyone else seen a QR code on the inside of the door of the 'secret stash' forge? I scanned it and it showed up as a phone number - not one in my country, but anyhoo. You can only see it facing away from the forge when it's closed, ie using clipping to your advantage.
Who knows whether it's actually anything, but I was interested enough to see whether anyone else had noticed it.
There are ways you can look this up without a smart phone. The number puts you on an answering machine asking you to leave an email address, platform you are using, and your user ID (gamertag/steam/whatever they call it on PSN). It promises little, but says you might get something from it (maybe a code later, who knows... maybe spam? XD)
