Steps to confuse a flexus card.
- Have a ticket due to run out at 21:39 2nd feb
- Add a new 30 day ticket on the 1st feb
- Go to Ullevål Stadion on the 2nd at about 19:00
- All validating machines "No valid ticket on card"
- Payment machine shows both active ticket and new ticket and can in fact print out a receipt showing so
And there we have it - I'm confused.
