Bug still here from last year.
When a player that was ranked as a top 100 prospect from another league (Indy league in my case) is purchased, he is put on the top 100 prospects list for his new league bumping better prospects off despite having inferior ratings.
I use annual list so it shouldn't even been updated.
Example...
Brown and Sherman are recently purchased players from the Indy Leagues and Frost was the #1 prospect for the Padres.
