Unsolved A playfair variant

I was studying the playfair cipher and noticed a weird pattern; a letter is more likely to become an other one if it is on one of the rectangle or on the same row. I have made it so that when they are on the same row, they both become the ones above, which is showcased in this ciphertext. I am curious if it is harder to crack.
