[CHAOS] Using Keys on locked Level doors

[Adny]

And that error occurs when you try to use the level door, right? If so, tell me all of the information you have on the level door (entity tab when you select it); all it needs to function is the name of the next map and and the player start area. Make 100% sure the next map is in the same folder, and that everything's named the same thing in the level door's settings, and in the next level.

If all of those things are correct, it should work properly.

You truly are the FastHunteR when it comes to scripting errors ^.^
