Custom Story Message Problem

[Anonymous2343]

I am in the progress of making a custom story, and I have it so that it displays a message when you walk into a script area. It's set to show for 1 second, but it doesn't go away, it just stays up. This is the code:

Spoiler below!

void Spawn_Library_Monster_1(string &in asParent, string &in asChild, int alstate)
{
SetMessage("Messages", "Message01", 60.0f);
SetEntityActive("servant_grunt_1", true);
AddEnemyPatrolNode("servant_grunt_1", "PathNodeArea_1", 0.0f, "");
AddEnemyPatrolNode("servant_grunt_1", "PathNodeArea_2", 0.0f, "");
AddEnemyPatrolNode("servant_grunt_1", "PathNodeArea_3", 0.0f, "");
AddEnemyPatrolNode("servant_grunt_1", "PathNodeArea_4", 0.0f, "");
}

What is wrong with it?
