We need help with creating a campaign.

She only needs to reach the garrison. That's what I'm trying to do. But the problem is that the script blocks the region, not for her, but for me:(

SetRegionBlocked( "region name", true, PLAYER_2 );
It seems you are setting PLAYER_1, but you need to set PLAYER_2 (I understand that there will only be two players in the first mission).
