Just like to add that I have heard of this in Squad which is currently UE4.12, I believe if the level is of certain size, and perhaps happens more if installed on HDD then SSD, it’s possible for a player to load in before the ground terrain or other objects have thus the player falls. I’d guess the best way to try to repo is have the project on hdd and a use sub level that has a very large terrain and possibly with other sublevels. Now the above is in regards to using level streaming without “ShouldBlockOnLoad” but I believe all Squad maps are set to “always loaded” as has pointed out using seams ‘ShouldBlockOnLoad’ doesn’t work.
