The tracker module died on my installation. This after I upgraded from 4.5.0 to 4.5.2
I ran the upgrade script and this corrected the count of the comments in the nodes properly. But when I started to add more nodes after the upgrade I noticed that the tracker simply doesn't update. It's stuck.
To correct this I had to copy the tracker.module file I have in my previous installation. Now it is updating properly but I'm basically using a 4.5.2 installation with the tracker.module of the 4.5.0
So the fun is that with the new tracker.module of the 4.5.2 the comments count finally updates properly but only it. If I create a node and this node doesn't receive comments, it doesn't appear in the tracker, as if it was never posted. It does appear only in the case someone writes a comment to it. While the 4.5.0 version doesn't update the comment count but at least shows in the tracker when a new node is created...
