World Composition game crashes

I have issues with World Composition Enabled game, when I want to go to a location which is on another, not yet streamed level. I have no issues with normal streaming if I just walk and streaming happened when approaching to another tile. My game needs a fast travel feature, now it a simple setlocation of the player character. Though levels affected on new place start to streaming, it frequently crashes, see attached log.
My smaller problem here if crash will be solved that streaming of tile(s) usually needs more time and player fall because of landscape not yet loaded/showed. Despite to normal streaming I cant use streaming events, so I have no idea how detect the automatical tile streaming start and finish. (Where I can show a loading screen and waiting for when player can start). More specifically, I cant use get streaming level node for tiles, they return none for world composition enabled map. Any help appreciated, thanks.
