The Yorick changeshave introduced some pretty major tower targetting bugs.

His ghouls could attack me under tower without even getting targeted. They would just keep going on me while the tower shot other minions. Happened only one time though I think, maybe twice. Also the maiden wouldnt draw aggro either, she would be in range attacking the tower as the tower rotated betweens minions to attack. Cant confirm if the ghouls drew aggro to Yorick properly.
