Server roll backed?

I did cube on my gunslinger last night at 10:47pm. I opened up the box and I got a precision dagger legendary engravings.

I was so happy that I registered it to auction right away.

Now I joined the game, engraving book is gone and only diamond cube box left in my inventory.

As I open up the box, of course, I get purple engraving book.

give my legendary book back please!
