darkhorse, question for you? When exactly has the "disappearing player" bug occured? I have run a historical league starting in 1901 and currently in 1914. I started using Cleveland and in 1911 switched to the Cards. On both of my teams I never had a player disappear. Also, I "player track" all the big name players to see if their OOTP careers will mirror their real life careers and none of them disappeared either, and in 15 years I probably have close to 40 players being tracked. I have read other posts where it seems players disappear when you have more than 40 total minor leagues or at a certain level or something along those lines. Is this when players are disappearing for you or is it always?
The thing that I have done to limit the number of players each year in the draft was delete all players with less than 100ab or less than 50ip, and early on, that's about 1/3 of every draft class. Don't know if just a mass amount of players is causing the disappearing bug, if so, maybe you can try that as it seems to work for me.
Either that or hope this patch fixes it
