I use autonav all over the place, but only in one spot is it acting peculiar.
The thumbnail is shows is not accurate. It is showing a completely unrelated image for 2 of them and an old one for the other. I have updated the featured image repeatedly on these pages, but it still insists on showing this one. As a sidenote, for the two that are identical, that image has NEVER been the featured image for those pages. It's for something else entirely.
