Hello there, Thank you for reaching out to us. We understand the [i]No Peeking[/i] triumph appears to not be working as it should be. This does sound odd to us. So we can effectively investigate what you're experiencing, please consider using your platform's share feature to capture a videoclip of the issue. A clip which demonstrates you closing each darkness rift and the triumph not registering your progression would be ideal. If you record such a clip or series of clips, you can upload them to a site like Youtube or Imgur, and link us to them here. We'll then investigate.
