When attempting to import this, the unity editor will crash.

1. Create a new project.
2. Open the Asset Store. (Window -> Asset Store)

4. Download and Import the asset.

Expected Outcome: The asset imports into the project successfully.
Actual Outcome: The editor will crash.

Note:
- Package requires Unity Pro to work.
- In editor versions where it does not crash, there is an 'API Update Required' dialogue we don't see in editor versions where it does crash.
- Can't find stack trace in the editor logs.
