Hello Markus,
I figured out a temporary fix for the bug after thorough research through the game.
Since the leagues including international teams was already created, I always received the ERROR message when continuing the game. The game pauses at 44% Creating / Checking Parent Team Logos… Then it asks to select OK and then it proceeds to playing game.
First, I went to the team Caffè Danesi Nettuno in the Italian Baseball League. Then I went to team settings and changed the city/name to Caffe Danesi Nettuno. Notice I changed the è to e.
Then I went to modify team colors, logos and textures. Selected "generate random" for primary logo. Finally, the game created a team logo with a "C" inside of bats.
I restarted the game and received no problems or errors.
However! It still happens when creating a New Standard Game with international leagues especially Italian leagues.
So to conclude it seems that the error is due to the letter è for the team Caffè Danesi Nettuno. It needs to be changed to a regular "e" in the DATABASE. Hopefully this can be fixed.
