When I start building a new deck from scratch, Lim-Dûl's Vault is found by fuzzy correctly even if I write it with a
simple 'u'. If I copy-paste the correct spelling, fuzzy finds it 'again' which is not a big deal. (see fuzzy.png).
However, if I have the deck saved and try to modify it, the card is not found, even if I use the correct spelling. Happens with both the text and the interactive deckbuilder. (see cantidentify.png)
Even more interestingly, in the deck list Lim-Dûl's Vault has the correct hover image but says Unknown card.
