Today I came across a strange problem. I wrote a Vehicle AI blueprint in which the vehicles travel along a spline. For that I have a VehicleRoute blueprint class which has a DefaultSceneRoot and SplineComponent and some custom variables and methods. At first there was a Sphere object where the spline started and the vehicles hit that sphere. I replaced the DefaultSceneRoot component with the SplineComponent and the sphere disappeared, but the sphere component switched to PlayerStart. It moves with the PlayerStart and even if I delete the PlayerStart, it stays there! How can I remove this sphere?
