Problem 59 of the Project Euler seems to have incorrect (old?) answer. cipher array that’s included in code appears to be from the latest version of the challenge, but 107359 result does not correspond to it, as that answer is correct for different array with codes to decrypt.
I have moved this post into a more suitable subforum. Generally, the #support sub-forum is for admin/account related support, and the #contributors sub-forum is used to discuss potential changes to the freeCodeCamp platform.
Once an issue has been discussed, it can be decided to open an official issue on the GitHub page.
