[Replicable] Blueprint Spline Causes Crash

Spline component causes editor crash with interesting crash report -

Assertion failed: Position.Points[Index - 1].InVal < Position.Points[Index].InVal [File:D:\Build\++UE4+Release-4.16+Compile\Sync\Engine\Source\Runtime\Engine\Private\Components\SplineComponent.cpp] [Line: 140] 

Steps to replicate -

  1. Create blank project (with or without content)

  2. Create blueprint

2 a) Add Spline Component

  1. In construction script, use “Add points” with update spline True, to add 2 any points

  2. Compile to crash the editor

I don’t see a reason for the assertion failure to occur.

Hi Crispy_Penguin,

Thank you for the report. This is something that was fixed internally and is planned for the full 4.17 release.

But how do you manipulate it ? cant break the struct and the only way to set the members is manually in details panel.
