Police write wrong court to appear on Nevada speeding ticket?

[Mo Z]

I got a speeding ticket at Nevada 3 months ago, and I was ordered to appear in court (Laughlin) in early September. So I called Laughlin court every week for three months until the court appearance date had passed, but they always told my record could not be found. I thought my case was dismissed. However, today I received a bench warrant from another court of Nevada (Searchlight), saying I did not show up on the court appearance date and would be arrested if I did pay the fine ($300) withing 15 days. So the police must have made a mistake by writing down the wrong court to report on my speeding ticket. What shall I do in this case? Is there a chance that my case could be dismissed because of the wrong court house on the speeding ticket?
