[2020] Mortal Reminder didn't get 10AD as the patch notes said, it lost 10.

In the 10.25 patch notes, Mortal Reminder apparently got 200 gold cheaper, while also getting 10 more AD.

However, the item didn't get 10 AD. Rather, it lost 10, making it even weaker (in terms of gold efficiency), which seems really contradictory considering they're trying to buff marksmen.

Either the patch notes aren't listing the intended changes, or the 10 ad nerf was a mistake. I already tried it in practice tool and the 20 AD are correct.

I'm really confused about this change. I really hope there was some mistake, since I don't see how this item deserved such a nerf while every other ADC item got buffed.
