Description

After project was upgraded to 4.12 opening a blueprint that contains Hierarchical Instanced Static Mesh component will result in a crash. From the log I this is the important part:

Assertion failed: InComponent->InstanceReorderTable.Num() == InComponent->PerInstanceSMData.Num() [Link Removed] [Line: 756]

Removing the component before upgrade will fix the problem. I re-added the component and re-set the nodes exactly like they were and everything works now.

Steps to Reproduce

1. Download [Link Removed]
2. Open the project and load "/Content/Outotec/EWT-40/Blueprints/BP_AutoCrane"
3. Crash
