Phone destroyed, wrote down wrong key, how fucked am I?

Not your keys, not your crypto. I know, so I need some help.

My phone got totalled recently in an unrecoverable way, so off I went to back up my wallets for the first time only to realise that for my Pera Algo wallet, the official one, I'd only written down 24 of the 25 words of my seed phrase.

I can't scan the QR code or get the seed phrase from the app on my previous phone, as its currently sitting underwater off the Suffolk coast. I have quintuple checked, I haven't written it down anywhere else.

I have recovered my other wallets, but is there any way to access my Algo, or has this been an unfortunate and expensive lesson for me?
