Multiple Hits per Object


I’m running into an issue when using the LineTraceMultiByChannel function.
After an initial collision with a volume, any further collisions with that same volume are ignored.

e.g. A line trace through a hollow cylinder (brush or static mesh) will only return the first collision.

The collision is not blocking: any subsequent collision with different volumes is also detected.
This problem seems to exist in Unreal Engine 4.13.1, but not in 4.13.0

My problem can maybe be better explained by this similar issue:

Any help or advice is greatly appreciated.
