I was just over at the token shop absently, and the new shirt... apparently is negative one in stock XD Did someone like...click on it at the exact same moment as someone else?!
Yea I thought it was too weird too! I thought i might be going nutty when I saw it.
As often as you hear about it happening, I have never actually SEEN it...so it was like, woah, double take lol

I've seen it a couple times, and it actually makes me chuckle a little bit--computer out-smarted by overzealous clicker-fingers. Teehee.
Face it, everyone wants to be a Leidina. ;)
It happens often, actually. Two people fight for the battle for that last one in stock and the shop can't determine which clicked first and goes into a crazy state of -1. :(
Oh my.
That's crazy.
I wonder what it does to the calculations in the server after a while.
I was always wondering, when two people click to buy the last item at the same time, do they both get it? :
Hrmm. You should restock it to fix it...
...Just kidding. :P
