If the user has not used Bisq since more then a month he should update to latest version and then delete some files in the `db` directory inside the data directory. Then those files get replaced by more recent ones which go shipped with the latest binary. that avoids to need to download the missing data from seed nodes (seed nodes have limits as well of amount of delivered data).
