Incorrect collision created when using merge actors to a specific spline mesh

Incorrect collision created when using merge actors to a specific spline mesh

UDN
Description

Merge Actor still can create incorrect collision when using merge actors to some spline mesh. This seems to be a mesh dependent issue. If I use different meshes for the spline mesh, the collision seems to generated correctly.

Steps to Reproduce
  1. Open the attached project
  2. Check SplineTestMesh to ensure the simple collision box is in the correct place
  3. Select SplineMeshActor1 and/or SplineMeshActor2 and use Window > Developer Tools > Merge Actors(make sure Merge Physics Data is enabled)
  4. Check the merged actor's collision - simple collision is created out of place
