Hi Elliot,
Sorry for the confusion. I was trying to say that I think the the wp object error was related to the fact that the field (in our case) never finished processing. I concluded this based on the fact that we were seeing the same result before and after the wp object fix you implemented. Once I limited the scope of the posts that field was trying to query against I wasn’t getting the wp object error and the rest of the edit page was being processed appropriately.
