I could have sworn I got reputation for the dfsr tag wiki and dfsr was merged with dfs-r recently too. Now the tag appears empty. 

I also believe the Kerberos tag had data but now doesn't. I have proposed some tag wiki content for it. 

I wont check all my tags but will be disappointed if time spent getting some useful in them has disappeared.

Just wondering if there are any known issues with tag wiki content going AWOL?
