What does preserving trigger do in the conditions?

Crash the game I would think. Preserve trigger is an action, not a condition. And it is ment to allow the trigger to run multiple times.
Preserving trigger in the conditions?? No idea what you talking about...
But neways, Preserve trigger "preserves" the trigger. Without it, once the trigger is executed it becomes obsolete and unusable. Preserve trigger saves the trigger after it's first use and can be used over and over again.
I'm also closing this topic. If you're going to ask a question, ask it once.
