Slight error in SOP - will it hurt me?

[QuantumDancer]

So, in a school I applied to recently, I said that part of the reason I was so attracted to them was that they had two accelerators on campus. Only as it turns out, they have three - they got a new one in the last couple years, and their website just hadn't been updated everywhere to reflect that. Will this hurt me, and if so what can I do to mitigate?

Thank you.

Chill, they probably won't notice either.
