[Bug] Material Translucency Broken?

So Im working on a shader for clouds when I stumbled on these weird translucency artifacts.
Basically just having a material with BlendMode set to Translucent makes some parts of your model disappear.

How to replicate:
This issue is quite easy to replicate as all you need is to make a new material with blend mode set to translucent and a mesh that eventually overlaps itself in depth. Or also just 2 different mesh planes that intersect each other.

More info:
On 2 intersecting planes the issue goes away oif the camera gets within a certain distance of the intersection. Only with the planes.
I’ve tested and validated this problem in 4.14.1 and 4.12

Question is:
Am I setting up something wrong? Or is the engine not yet capable of this?
Any help or info is greatly apreciated, thanks.

Below are some caps of the issue and what it should look like

This is, (as far as I know) normal behavior with translucency due to the differed rendering and translucency sorting order.
You can try setting the sorting order of the meshes (either in world or trough blueprint) but that is about as far as my knowledge goes on this matter.
