I'm not sure how many weapons are affected by this one, I know the Apex Predator, Heretic, Sleepless, and Ascendancy (all rocket launchers) aren't loading in the weapon preview. This one only really causes me heartburn on the Apex Predator because I want to preview potential memento shaders. I haven't noticed any other weapon types not loading, but I may not be noticing as my primary and secondary pull only from a relatively small list.
