Losing points and demoted to Active Contributor Silver

Hi Experts,

Sometime back I received an email as Acknowledgement of Achievement for becoming the Active Contributor Gold.

However today I faced a strange problem, after releasing a Jive Document my points increased to 1510 however after some time it drastically dropped to 1232.

Moreover I no longer remained Active Contributor Gold.

Can someone please tell what has happened which has led to losing points and demotion?

Thanks,

Saurabh
