in my level only has 2 object like this. one chaos geometryCollection , and FS_MasterField

geometryCollection initialfield use FS_MasterField like this
in the pie aways normal, but when i build the project for windows.
if the two object under levelinstance

the FS_MasterField will be useless, the box will fall down.
but if don’t under levelinstance,it will be ok. How to fix it? it’s a bug, or setting?
i guess the leveinstance cause the geometryCollection lost the reference about FS_MasterField
