Greater Stone combination fails! Fix the chaos machine please

[leechiupin 1]

I have spent tons of my Jewel to make +9 +16 anc items to the Chaos machine in order to get Greater stone.

It wrote like I will get 1-2 stone if it success, but I failed 3 times and I got 0.

Is that normal or the bug?. By the way, it never happended to me in the Prime server. So whats the difference?

Please help me and the others, Im realizing that not only have kind of this problem.
