old h1b revoked

I started working for COMPANY A who filed my initial H1b in 2012. After working for the company for about a year, I joined a different company B. They filed for transfer of my H1b and I got my new H1b approved in Aug, 2014. I have been working for the company for months now. Few days ago I got a email from USCIS that my old H1b is under processing and later I received a email saying my old H1b has been revoked. I logged on USCIS which shows my old H1b with company showing revoked status but my new H1b with current company still showing approved. Kindly help me how does this affect my current visa status
