Wallet loses tx key and transaction data - possibly caused by reorgs

[DrFredPhD]

For years of use I've had an intermittent issue with the wallet file losing track of tx key and receiving address of outgoing transactions. I mainly use the cli wallet and have no idea what causes it. Since first running into the issue I've religiously closed the wallet with the 'save' command, followed by 'exit'. Usually after a transaction I'll use 'show_transfers' and the receiving address will be visible and 'get_tx_key' will work. At some point in the future I can reopen the wallet and that data will be gone and 'get_tx_key' will fail. (Loading the wallet in the gui also does not help)

I initially had no idea what caused it, but recently I noticed one of the transactions I lost data for was one that was initially included in a later orphaned block. Perhaps the wallet loses this data if the original block a transaction was in is reorged out.

Sorry, i thought i opened an issue for this already (i did not).

#8372 (comment)

The reorgs DO mess up wallet history, dropping tx details.

tldr: yes, the cache drops all knowledge of the tx when it gets sent back to the txpool. Probably also related to #10013 - when it is sent back to the txpool, the wallet might even forget the tx exists until it is mined again.

I've experienced the entire tx disappearing from my wallet history, and reappearing when mined (sans-details)

Yes the tx disappearing entirely then reappearing without info is what finally made be realise it was due to orphaned blocks. If there any way of this being fixed? Or do I need to manually copy out recipient and tx key acter each transaction if I think I could ever possibly need it in the future?

Is this with a Trezor?

With all wallets
