FMC not showing changes in previews

[atsukane]

Hi all,

Not sure when this has started happening but my FMC stopped showing changes in the deployment screen, I just get "No changes found. Unable to generate diff. Please try a successful deployment and try again.

However, even after successful deployment I'm receiving the same message.

Preview in the Deployment History is also the same, not showing anything and I get orange triangle with exclamation mark, 

I've restored from a full backup to a new VM but this has not resolved the issue. 

FMC is 7.1.0.1 and FTDs are 6.6.5.

Has anyone seen this issue, and how did it get fixed?

Many thanks,

Opened a TAC case, apparently this is a bug CSCwb75373 and fixed in version 7.2:

Updated FMC and FTDs to 7.2.4 and the preview id working again!
