Were they open? If they hadn't had time to open, you'll be alright. Hermies can be treated. I'm about to harvest 7 gals in a few days, 5 hermied on me for the last 3 weeks of flowering. Spending about half an hour each day combing through each gal, I bet I haven't got more than 15 seeds in the whole harvest. These last couple of days I couldn't care less, it's too late for pollen to ruin my crop, I'm home free.
Interestingly, the bananas have stopped, now that the flowers are almost mature.

Hermies can be saved, if you're willing to spend some time on them.
