Current questions and answers regarding the map editor.

Today, I encountered the following problem: I placed a couple of effects (PlayVisualEffect) on a test map, linked to coordinates, and everything worked perfectly. I copied them to another map, and one effect works, but the other doesn't! How is that possible?! I thought maybe the lighting was different? I changed it, but it didn't help. I linked the effect to an object, but it still doesn't work. I changed the coordinates, and I changed the level from a dungeon to the ground. I don't know why this is happening anymore; what else can I change or adjust? Maybe someone knows why an effect might not play.
