Procedural meshes crash and go missing in blueprints

Currently I’m creating procedural mesh component in 4.16.2 and slicing them with a projectile.

Also procedural mesh components are removed from blueprints that use them. I’m not sure what’s causing this but as it stands now procedural meshes are completely broken.

Crash reports don’t produce much unfortunately. I’ve tried messing with a few ways to build procedural meshes, but I’ve taken some screenshots:
