Bitcoin Core developers warned users on Monday of a wallet migration bug in versions 30.0 and 30.1 that can delete files and result in fund loss.

The issue occurs under specific conditions and affects migrations from old Bitcoin Core wallets that were never renamed or upgraded.

Lacie Zhang, market analyst at Bitget Wallet, told Cointelegraph that the bug is triggered when the software attempts to migrate an unnamed legacy “wallet.dat” file stored in a custom wallet directory, often defined using “-walletdir” setting, while pruning is enabled.

Honestly, this kind of bug is embarrassing. Core should've switched to deterministic wallet at least a decade ago.
