Hey, I don't know if it was added this update but I found the locked box that you buy from the adventurers guild and well, I'm not good enough at riddles, I have some ideas for it but in the end I just have no idea what I'm doing.

from left to right the first flower is blue in the first column, so blue equals 1, pink is in the third, orange 5th, white 7th. so the numbers for the code are 1 3 7 5. i already opened the box so i don't remember the color order. i'm also not sure if the road counts as column, so pink and orange might be +1
