It happened in an update earlier this summer. 

The warning that the 1116B needed to be attached prior to getting the rejection is a great feature, but it doesnt need to be so clandestine!  LOL   

The EF Info Worksheet makes NO mention of WHAT needs to be attached, it just gives the red error next to it on the Forms in Use list.  When you go to it, you get nothing that tells you what it wants attached.
