Missed trip that was already added to the pass. Can I use the same QR code to get on the next train?

Hi Eurail Community

If for example I missed the trip that I added to my Global Pass, noting that this said added trips to my Global Pass has already a ticket, can I use this same ticket on the next train without having to browse for next train time schedule, saving next train tome schedule to my journey and the adding this to my Global pass to obtain a new ticket? 
what will happen to the first ticket that I missed — is this forfeited?

thanks
