Editor Crash Once Make Stream Level Visible

Hi there,

I’m trying to load a stream level at game start and if I check “make visible after load”, the editor will go crash once load finishes; the same thing happens if I load the stream level at game start without checking “make visible after load”, and manually set “should be visible” value to true after playing for a while.

I’ve tried loading a clean level and check “make visible after load” and the editor won’t crash, so I guess it’s the very level map that causes the crash, but I’m not quite sure what kind of settings in this map is bad.

Here’s my crash report and runtime log. Any suggestion welcomed.
