Definitely disappointing to get the RFE. I got one too on April 1st, but like you, I was just happy that someone was looking at my case. The good news is that it only took USCIS (California) two days to approve our petition (NOA2)once we sent in what they needed. For us, it was that they needed the entire divorce decree with the judges signature, not the one page divorce certificate I got from the county clerk.
Good luck. I hope the RFE is something simple. Hardest part is waiting for the darn hard copy to come in the mail!
