Helo. After a month since the last activation of Bitcoin Core 25.0, I activated it again on March 20, also version 25.0, and noticed that some btc disappeared from my wallet. There are no transactions in the wallet during this time. I saw on bitcoin.org that there is BTC core 27.0. After launch v27.0, the same thing. I deleted everything from the wallet directory and downloaded the blockchain from the beginning, changed wallet copies, but BTC is still missing at the end. What could have gone wrong? This is the first time in a dozen or so years that I have had such a situation.
