They could identify partial characters but could not reconstruct the exact BIP39 words

Blocked

Case description

A user had split their 24-word BIP39 seed across two sheets of paper stored in different locations. When retrieving them in 2015, they discovered one sheet was partially water-damaged and five words were illegible. They could identify partial characters but could not reconstruct the exact BIP39 words without professional assistance.
