Stadium changed mid season

We have a franchise league going.
Though 75 games, the Yankees played their home games in Yankee Stadium '48.
Last night against my Red Sox they played games 76 thru 78 at home in Great American ballpark

This is a huge problem. Kind of defeats the purpose of starting LH Pitchers against them.
Joe Dimaggio hit 2 ball park HRs.
His chances in Yankee '48 were 1-6.
Last night they became 1-13.
This is wrong.
This needs to be fixed ASAP.

I've contacted support again to switch the stadiums and address the glitch.

Just for the rest of us unknowing
How did this happen - don't see anywhere that a mgr can change stadiums after the draft.

One of the many many things they missed when double and triple checking stuff.

It happens when you have multiple tabs open while creating a new team - the system gets confused and crosses up the data. In this same league, I had a team switch out of active league and into the new league, leaving a league 3 weeks into the season with only 11 teams. It was fixed by support immediately, and they are looking into the issue.
