The issue with the "unknown card name" message being shown for all cards in large collections has now been fixed, thank you for reporting this @Ober25.
Other changes:
- You can now specify a maximum deck age in the collection deck tutor
- When you build a deck from your collection, cards you add to your deck will be added with the set you specified in your collection
- The deckbuilder now has a maximum width, which means it won't stretch out too much anymore when you have a very wide screen
