Spline mesh disappears when aligned on z axis
Using 4.18.1 I have found a very specific case where spline meshes appear to be failing when it has two points aligned on the z axis. First, let me detail what I was trying to achieve:
In the construction script (this also applies to the normal event graph as well), create the graph as shown in the following image:
In the Add Spline Mesh Component, select the mesh SM_PillarFrame, and the forward axis as Z, then compile. In the viewport, you should see the mesh aligned along the x-axis as expected. Now translate key 1 of the spline to position [0, 0, 100] and the mesh will become hidden.

Hi Dr. Widget,
I was able to reproduce this behavior so I've created JIRA UE-52947. Our developers will be investigating further. Follow that link to monitor the status of the issue on our Public Tracker.
In the meantime, the workaround would be to use the offset that is like you described above (0.00001).
