I'm playing on the Nintendo Switch. I've played all the way through the campaign and just started going back through the chapters to complete challenges that I missed the first time. I ran back through Cantlin without issues, Rimuldar though is giving me some problems. I completed "Obtain the Crowned Goowels" and "Complete all of Thalamus's puzzles", but the Rimuldar exit portal won't open. Is there something I'm missing? Is this a known bug? Any idea what's up?
