I actually attempted to repro myself before you posted that using almost the same steps, unsuccessfully. Basically, I wasn’t able to create a repro case, but it happens in every large map I have - it seems like just placing an absurd number of the same object isn’t enough to create a map that takes any time to load (or become visible) and cause the problem to manifest obviously. I feel like you’d be better off trying to repro at your end by streaming something that’s actual content, like ElementalDemo, into ThirdPersonExample or similar.
