I have wondered for awhile, when I start a game in 1901 I sometimes unretire a player. (sometimes a dead one) When I do that some of the other retired players disappear. When I start I think there are about 5 or 6 pitchers who won over 300 games, but when I unretire one there are now 2 or 3. sometimes Pud Galvin is not on the list despite winning over 360 games. What gives?
