Arcadia called me a Nord, even though I am a Breton

After experiencing difficulties with a stuck loading screen in Skyrim, I had to force my PS3 to shut down. Thankfully my saved file wasn't completely screwed up in the process.

But after I loaded my save game, I travelled to Whiterun to get some ingredients from Arcadia. Once I interacted with her, I was shocked to hear her say "Maybe a hardy Nord like you doesn't need a cure-all, hmm? What about an invisibility potion?" This isn't right. I am a Breton. I really hope this doesn't have anything to do with corruption in my save file.

I would like to know if anyone else has experienced this issue. I don't want to be confused for a Nord throughout the rest of my Skyrim gaming experience.

She says that to everyone, including my High Elf.

One interpretation is that she didn't call you a Nord, she called you hardy like a Nord. Bretons can be quite literal.
