Cards randomly removed from deck

{"ops":[{"insert":"I keep encountering a glitch that randomly removes a few cards from my deck when I close the tab or go to another section of the website. This happens despite the decks being saved. So far, I see no apparent pattern or solution. Pease fix this issue as soon as possible' it's been happening to me for months now. It's very frustrating having to copy the deck list and sort through the remaining cards and list to fix it every time I make a deck.\n"}]}
