Lost cards in a deck, twice.

{"ops":[{"insert":"So I've been having some real trouble building my Shirei deck.\n\n"},{"attributes":{"link":"https://archidekt.com/decks/725243#Shirei"},"insert":"https://archidekt.com/decks/725243#Shirei"},{"insert":"\n\nSo last week I built this deck idea to my satisfaction, but in making it I ended up breaking it out into an obscene number of sideboard categories, 14 as of now (not included in price, deck, and not premiere). After getting it to 100 cards I liked, I came back a few hours later to make an adjustment and I found it in the state it's in now; almost half of the main deck is suddenly missing completely, while the sideboard categories are untouched. They don't appear anywhere when editing the deck via text either. I worked up the nerve to redo it again today, but I took a look at it a few minutes ago and the same thing as happened.\n\nIt's not a huge loss but it's REALLY annoying and isn't something I've experienced in any of my two dozen or so other deckbuilding experiments, often with very large sideboards. I'm just reporting the bug, but if I could somehow get a rollback to the version with a 100 cards saved on 8/21/2020, that'd be fantastic!\n"}]}
