The Fractionated Morse autosolver picks the first placement of the crib instead of the one recommended for the question text #461

As mentioned in item 5 from #410 Plaintext: this is a siMPLE exaMPLE to try out siMPLE Keyword: KEY Crib: MPLE

The Suggest Question text gets generated as:

A quote has been encoded using the Fractionated Morse Cipher for you to decode. You are told that the quote ends with MPLE.

Which implies that the crib is at the end (as expected). However when you look at the solver, it picks the first occurrence of MPLE

With the crib of mple mapped to the ciphertext V S J A D X we now know the mapping of 6 characters. Since we are told the mapping of VSJADX ciphertext, we can build the following table:

The new code correctly attributes the location of the crib! Great job
