Can you show me exactly where in the korean patchnotes writes about this? Because when I read them i never saw something related to kinah. In 8.0 there is broker adjustment but in 7.9 has not anything regarding kinah.
Thats a 6.x "feature". One of the thigns that destroyed this game few weeks after the "blank slate" launch almost 3 years ago. First it was a bug with the inventory vendor, fixed by gameforge, later adjusted by them.
