Undocumented and/or hidden changes that were left out of the Patch Notes.
As you all are quite aware Kinkoid isn't good at communicating and quite often they implement changes that they don't include in the Patch Notes. We can only guess about their reasons of doing so. But it's the fact that those changes are made and there's not even a word about them in the Patch Notes. This thread is specifically created for the purpose of finding them, keeping track of them and discussing them.
