Yep. Happened last night too. I contacted EF about it. To their credit, they got right back to me and said that, basically, it's AA's fault. In other words, EF is working correctly, but AA is incorrectly showing the inventory. Apparently, this can happen when AA is updating their inventory buckets. From what I can see, award search for C (or A for that matter) shows revenue C/A in place of award C/A even when a proper award search is conducted.
