Archive.php 1.8.2 issue

I have notic one thing after upgrade of 1.8.2 its not updating my world map until unless i change General setting > Allow Piwik archiving to trigger when reports are viewed from the browser = Yes

I do have archive.php running every 1 Hours via cron. Everything i have to change setting archive trigger via browser. It was working fine on 1.7.x but after 1.8.x i have notice this. Did anything change with archive.php which i am not aware ?

Any one else have this issue ?
