I think there is a bug in the site: sometimes when i click on roll, it keeps on rolling and doesn't stop on a number. With refreshing the page this is solved (when i than click on roll - i get a number), but i have already had this a couple of times.
How often does it happen? What browser do you use?
Hi wetsuit: it happened to me yesterday 1 time (on 10 rolls) and today also 1 time (on 5 rolls).
I have had it with my mobile phone and computer (using chrome as browser)
Can you pm me your user id please, I'll take a look. Also which captcha are you using when this happens?
