Correctly given by Darren, it is definitely some javascript code that is sending an AJAX request (post or get) that is preventing the link from functioning as you would expect.
However, if you've used an external resource, it might be difficult to correct the error in the min files.
I suggest use a jquery onclick event inline to circumvent the AJAX call
You could additionally use window.open('https://www.foo.bar/culrsteam', '_blank') like with target='_blank'
