Cannot not save SHSH for 5.3.

I just upgraded 3 ATV2’s to 5.3 without any problems. But, i cant save the SHSH. 5.2 is still my newest backup.  

Is that a error or just the way it is? 

same for me here…

 

anybody an idea?

Same here.  Did apple dump signing 5.3 in response to the jailbreak or something?
