Yorick Unsaid Nerf

Basically whenever I play Yorick, I know they said there were damage nerfs but were there other nerfs that weren't said in the notes. The Maiden Ai seems different now. Whenever I go to attack the turret, the maiden follows and starts attacking the tower also. But when I back off, it takes way longer for the maiden to back off(lost my maiden several times like this). Same for champions. Did they change this? I don't really mind that much, but if they did, then I wish they would have put in the patch notes. Did any of you guys notice anything like this?
