Same as the sibling comment already stated, I was able to check in, and instead of being assigned seat 24B (or something of that calibre), my boarding pass said “seat assigned at gate”. I still had a valid boarding pass. Nothing went wrong at the airport, besides Ryanair failing to follow correct overbooking procedure. Fortunately in that instance, had they refused boarding on me, I would have suffered zero inconvenience, and have received 350 euros compensation and a flight the next day. In a way, I wish they had refused me that day.
