I was looking at -ex and saw that my site www.mydomain.com does not have a fresh tag when all around me do and googlebot came by my site on the same day. However, found that mydomain.com has the appropriate fresh tag from that last googlebot visit? Is that unusual? Might I have a problem from when I moved to a new server recently and that is why mydomain.com looks like the one crawled? But www.mydomain.com is showing well in -ex, but for how long I don't know, since it drops completely often?
Anyways, my question is more about the behavior of the fresh tag and mydomain.com vs www.mydomain.com
