Next Video is with the volume bug fix on…
I also showed the issue without sequencer direct so normal actors in the world also have this issue only outside this initial spawn world streaming radius.
With my game i have 2 crops and 1 mushroom plot all at different locations so the player will always be out of load range for something and the mushroom issue around the map when hitting it and its still got collision when its hidden ect is also a bug.

@Max.Chen Could you look at this please 
I can replicate 100% as stated Also i have listed the private codes if epic is able to wonder in and out of islands ect
ref to the other report i made for just normal actors
Problem 2 in this could be related
I can repro it 100% on this setup so this is a good tester for epic to find the issue
