Azrael's Trickbox shot up...

I just woke up at 4 am (yes I'm fucked up like that) and I found out all my listings for Azrael's Trickbox going at 95k had been sold and it went from 87k to 99.5k in one night.
Anyone know what caused this sudden rise?
Also, if you still have any, I suggest you sell them now, they'll never hit this high again.

yes they always rise in price every midnight-morning
i usually buy them in the afternoon and sell them at midnight for profit
