FC26 Team Sheets Bug

Since FIFA 14, my best friend and I have been creating custom tournaments.

We go into Team Transfers.

Move legends and random players to Europe’s biggest 16 clubs.

Then start a custom tournament.

We’ve done this for years with no issues.

Now we can’t do it anymore.

After transferring players to a club, Team Management freezes.

You try to swap one player.

It doesn’t move.

Lineups don’t save.

Formations don’t save.

That club becomes locked.

All other clubs work.

Just the edited ones break.

This started after the new Classic XI / Legends teams were added.

Is anyone else having this exact issue?

Is there any fix or workaround?
