Hi, i wondered if anyone could help me. The interail website is showing availabiltiy a 6 berth couchette on the 8th of August from Zurich to Zagreb. It allows me to add it to my basket and proceed to payment, but as soon as I click confirm it tells me that the journey is no longer available. But when i go back to search it still shows as available. Does anyone have an insight as to why this might be happening and whether the journey is actually available.
Thank you
