This also applies to simply naming a deck the same way yourself, but don't do that! (Don't be like me lol)

Steps to reproduce:
- Create a decklist as shown in attachment Decklist.png
- Import while said decklist is in your clipboard
- Deck selection is now bugged and potentially unusable, has varying results.
- Logging out or rebooting does not fix the issue.

Platform: Tested on both PC and Android.

Results: Deck selection has unpredictable behaviour, generally unusable.

Expected results: Either reject the imported name, or sanitize deck names.

Workarounds: Switching back and forth between Android and PC clients will sometimes make the bugged deck show back up, but trying to rename it softlocks the client. I did eventually manage to delete the bugged deck, but I'm not sure exactly how I managed to select it to do so.
