Anyway I'm at a loss. Any cool ideas I'll try them out for the benefit of the electrum community.
Well, if you think you may have made a mistake in recording your seed, you can give seedrecover a try (it's part of
btcrecover):
https://github.com/gurnec/btcrecover/blob/master/docs/Seedrecover_Quick_Start_Guide.md#seedrecoverpyIt's an open source seed recovery tool; it requires that you have a good estimate of what your seed is, and also that you know either your master public key, or an address generated from your wallet (preferably one that was generated shortly after your wallet's creation).
