When I go to the free credits page, after the first link I click, page reloads, and then when I try to click another one, the page scrolls up. 

This only happens when I click. It happens each time after the page reloads.

If the page is already scrolled up, I can click the link without any problems.

I use a browser named Chromium, which is basically Chrome but without the Google account requirements. 

I confirm this happens for me with Firefox and Chrome

As a reference point (if that's what this is), this issue doesn't occur in Firefox

This has been resolved.
