Main page play button bug

Not a priority bug but when opening the browser, either in chrome or mozilla. Once the play button has been loaded, clicking on it will open the games list. All normal.. But when clicking on a specific game a new tab opens, then the new tab opening redirects the page to the main page again.

But.. If you close the new tab inmediatelly, or after t has been loaded I can use either tab (or just close either one of them) to do the same process again and then the redirect will go to the right address (the game).

This also only happens when starting up the browser. So everytime I completely close the browser and reopen it, this will happen, if I leave it open but close all COW pages then reopen them whilst leaving my browser running this issue also does not occur.
