When playing the campaign, after the 2nd scenario, the game starts over with the 1st scenario. After finishing scenario 2, the next dialog and button shows up, clicking on that button and the goals are for the 1st scanrion, building I placed before are not there anymore, so it''s a clean reversal. I also cannot take a break quitting the game after scenario 2 is finsihed. Possibly related.

I own the game on DVD, so I know that there are many more scenarios to the campaign

Have the English Version installed. WIndows 10 (German), latest updates installed.

Found 2 solutions for this issue:

1) After each scnerio, the game creates a save game. Those save games can be loaded and the campaign continued from there.

2) Run the game with administrator rights.
