Sometime within the past few days, I noticed that a column from a parent content type is not being inherited by any children's content types. This is a custom column that we created that we use across all of our sites.
The problem is not site-specific, it happens on any site that I test adding the child content type to. One of the parent columns is not available.
Any way to troubleshoot this? I re-published the parent and child last night, and there is no change so far.
