Upgraded from 3.85 and featured item module now states
A critical error has occurred. Input string was not in a correct format.
Tried putting new featured module on page, same error
Can you try going into the featured products module settings and re-save your settings.

Odd, seems there was a category object on the page that maybe was messed up because when I checked it's setting it had an error inside it, I deleted it and the featured items came back... Image and link now going to details... nice...
