A licensee reported one of their map crashes on open when they tried to migrate from 4.12 to 4.14. There was no crash in 4.13.
This seems to be caused by a certain BP actor that adds InstancedStaticMeshComponent on its construction script.
1. Open the attached project in 4.14
2. open maps/untitled.umap
3. Editor crashes.
