If it happens consistently enough I would ask clients to try to keep track of where they are when it happens. If they are all near the same location then its probably a map, if they are not then the issue could potentially be a vehicle, or clothes maybe. It isn’t even guaranteed that the issue is a streamed asset, but its good to close all doors before deciding there is an issue with the main area, and IF DrawModelGeometryHook is what’s crashing them I imagine that would have to be related to some incorrect data passed from a model.
