LevelnstnceWillLostReferenceOnBuild

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

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
image

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

you can download the test project, the level named MainMap will find it.Thanks you help.
