[4.7.2] Editor Crashes on Converted Project With Instanced Static Meshes
Detailed description of the issue:
When opening my project in 4.7 - the splash screen gets to 95% Initializing before crashing.
Action 1: Create a content-only project in 4.6.1
Action 2: Create a blueprint which adds instanced static meshes via the construction script.
Action 3: Place Blueprint in a specific map
Action 4: Build Lightmass
Action 5: Convert project to 4.7
Action 6: Open map with previously created Blueprint
Action 7: Witness Crash
Hi VSZ and Kenomica,
I just submitted a fix for this crash, but unfortunately it just missed the deadline for the 4.7.3. Something seems to have changed with the way we fixed up components after re-running a construction script and it's affected the way lighting is reapplied to InstancedStaticMeshComponents.
The fix will be in 4.8, and a 4.7.4 update if we end up making one. I think this fix is pretty important so I'll push for it.
If you're using source code you can apply the fix directly yourself:
Thanks for your patience and help reproducing this bug.

Is it possible you are using content from an old sample? There are some known issues with opening very old assets with 4.7, please see this post: https://forums.unrealengine.com/showthread.php?57455-Old-Sample-Content-in-UE-4-7-IMPORTANT
