Hi cardcore, please rest assure that the game will not cause a player to lose any card without manual operations because the data are stored on our server. If we want to check how and when the card was used, we will have to have the developers to spend a really long time looking through the log, especially when you don't know the approximate card missing time. The developers helped checked a dozen times before, but every time after spending quite a long time, they only found the log that the player used the card in the strengthening without noticing.
Enjoy the game!
