I made a ‘pathconstructor’ blueprint which has 2 spline components. Then in the level sequence i added that bp and an empty actor tracking the path of the ‘patchconstructor’. In editor it follows the spline i want it to, but in the packaged build it switches to the other spline. Since i cannot specify the spline component it needs to track, it picks a certain one which is different in editor and in build.
I solved it by removing one of the splines, but this should be a bug.
Extra info: One of the splines in the ‘pathconstructor’ i’m tracing to the landscape on construction.
