Bone rewards bugged?

Hello guys,

I don't know why but I don't get any rewards from bone anymore. I tried it now two times. Every time when I beat the dragon it just stuck at the battlefield. I can still move and use all my skills. That shouldn't happen.

shouldn't happen that often. But it happens. I've got no idea why it happens, you're just going to have to hope it won't happen to you very often

Had it once in 25 bone , you just don't are very lucky xD
