A couple of small improvements shipped today:

Duplicate disc detection - There was an issue where users were able to create duplicate discs. I think that is solved now, but we'll continue to monitor.

Duplicate plastics detection - There was an issue where users were able to create duplicate plastics that shared the same flight numbers as the parent disc. I also think that is solved now, but we'll continue to monitor.

Cleaner disc details - On the collection view, fields like Year, Purchase Date, and Purchase Price now only show up if you've actually filled them in. No more rows of dashes for empty fields. This affects the website version only.
