4.13.0 Spline set closed loop to true causing crash

One of my actors uses a spline to determine the position of a tank track mesh. Any time I tried to open the blueprint I get a break point at line 158 of SplineComponent.cpp.

I changed the c++ base class so it’s not a closed loop, the BP opened fine, then I tried to change it back in the BP and I get the same crash. As far as I can tell, calling ClearSplinePoints(true) with a closed spline is causing the crash.

Hey Skuvnar,

Can you show me how your spline is setup? Or describe in more detail how it is setup.
