Spline Mesh Actor Crashes engine on reimport

The Editor crashes when a mesh that is used in a Spline Mesh actor is being Reimported.


  • Add a Spline mesh actor to your scene.
  • Set a static mesh into the Spline Mesh Actor.
  • Set Collision of the Spline Mesh Actor to Block all
  • Reimport the Mesh
  • Unreal Crash.

This only seems to happen when the collision is set to Block all.

Is there a way around this crash as its slowing down production quite a bit.
