I don't know if it's a known issue.
I play the Owner Mode and I created a player during that Owner Mode with the internal editor.
And if I search his name and click him to edit him he gets bot the hitter and th pitcher tab although he is a hitter only (RF).
But what's even worse is the fact that a some other pitchers in that Owner Mode get their stats deleted once I clicked to edit the created player.
Those pitchers are not only on my team but all over the leagues.
They only have a fastball and a changeup but all values are 0. Almost like what the created hitters has as pitching stats.
Is there anyway to deal with that issue? Except not editing a created player.
