If you're on good terms with hubby, time to sign I-407 and restart process.
Your current GC is dead. It'll be caught. Better fix it right now.
There was a poster here a while back who got ROC without interview, and during that time, she'd divorced (I think she was waiting to got to interview and present divorce papers but got approved without interview and just sat on the divorce papers). Anyway, she applied for N400, got caught and was thrown back to go fix her ROC.
