Is the Red X under the enemy hero? If so, they have bad code and there is nothing you can do about it. This is a well known problem with the multiplayer levels.

> @Chaboi_3000 Who can change the Simple, Easy, Hard code selections when starting out in the Multiplayer? When playing Blue in Harrowland, the Simple CPU code locks your code up and you can’t complete the level. Even when playing red, the enemy code doesn’t work, but you don’t get locked up. Below is a post with a video showing the code being locked up when playing as Blue. I switched the opponent to the Easy enemy and it worked.

Is this one of the CPU opponents? Try to pick another opponent to fight. Sometimes it will let you, or go to the ladder and select another opponent to fight.
