Spectre Carnage Chieftain does not scale

Hi,

Taking in act 2 'The old fields' The carnage Chieftain as a spectre and summoning it again in high level map does not scale his life and it seams the mob stays low in life.
The consequence is 'one shot' on first attack.

Regards

Sorry my fault. as an idiot I was using my low level desecrate.
