Events+ is not removing RSVP'd users after an hour

Hi,

Events+ isn’t removing unpaid users who have RSVP’d after an hour.

I only have Events+ installed and am using the default WP 2014 theme. No other plugins have been installed as this was a test site for a previous IPN issue with Events+. This was occurring on my clients live site prior to the fix, so it is unrelated, but still prevalent. I can provide access again to this site if required.

Thanks,

Martin
