Description

Switch Skeletal Mesh node crashes the editor if the blueprint is compiled after changing the mesh being called on node.

Frequency: 3/3

CrashReporter: N/A

NOTE: tied to [Link Removed], however one crash occurs during PIE, the other during blueprint compilation.

Steps to Reproduce

1. Download, unzip, open project at link (password is 19941129):

[Link Removed]

2. Open Content>CarTest>Blueprints>HOLLO>HOLLO
3. On "Set Skeletal Mesh" attached to output "B", change the new mesh to HOLLO_MESH_UE2
4. Click the Compile button

Results:

Editor crashes

Expected:

Blueprint compiles.
