Where has the karma gone?
The karma is not being displayed on the posts, but mine is still accurate. If you log in and click on your icon on one of your posts, you should see your karma, along with the rest of your profile stats.
My karma is still not accurate if I log in and click on my profile icon at the top of the page. It shows my karma when the upgrade was done.
Mine's been updating, I think it's correct. I'm reasonably sure it was showing next to posts as recently as yesterday, perhaps even this morning (it's late afternoon here now).
You could look at the 'Karma" thread to get some ideas on what may have transpired.
