Apparently this got crossposted.

Cube Litening C68 Snapped off Rear Derailleur | CycleChat Cycling Forum

Anyway, my interpretation is that this is a poor design. The derailleur hangers should be engineered to fail without also taking out the frame..

In this case, there seems to be a descending portion of the frame that is bolted to the derailleur hanger, and a failure of the hanger will necessarily also take out a chunk of the frame. It really should be designed so that the wheel primarily holds the hanger in place, and failure just rips the hanger apart.

Of course, loose bits around the rear of the bike is never good.

Anyway, take it to the shop and see what they say.
