I figured out why I was having problem with my stadium
-
For lack of a better term my stadium was "crashing to desktop" during games. By that I mean it would leave the game and go to the front page of the ps5 listing all my games. I then clicked on the mlbts25 logo and it would return to the game.
The reason was I ringed my stadium from foul pole to foul pole with the orange trestle tower. I used to many that the game wouldn't allow me to use any more. I was able to save and use the stadium but it did what I described above. I deleted them all. No problems.
I'm posting this in case someone else has a similar problem.
