SEO: 1.3.3
WP: 3.5
Started with: 10 or 12 posts with "Green Lights"
Next: In the WP Posts view I "batch edited" those same posts to add 1 tag
Result: All the green lights turned yellow.
Me: "WTH?" :)
Going back into any of those posts after and changing some minor detail (other than the tag) and updating, turned it Green again. So somewhere in this mix either WP 3.5 or SEO 1.3.3 is getting confused and re-rating posts when it shouldn't be.
