The seed structure of my wallet file is defined by a much longer string, containing several groups of alphanumeric data joined together by plus signs, with an equals sign at it's end - and the 'seed version' of the wallet is defined as 18.
I am attempting to discover why my wallet is so different in it's wallet seed structure and seed version number to the other electrum.dat wallets i am able to create using the older releases of the client.
That sounds like base64 encoding, which suggests the seed is encrypted. Are you by any chance comparing a wallet file that has a password set with one that does not?
