Actual result: “Exception: Scene Hash 498439127 does not exist in the HashToBuildIndex table!” exception is thrown

Reproducible with: 1.13.0, 2.2.0, 2.3.2 (6000.0.50f1, 6000.1.6f1)
Couldn’t test with: 2022.3.63f1, 6000.2.0b4 - Compilation errors prevent the reproduction

Reproducible on: Windows 10, Windows 11 (user)
Not reproducible on: No other environments tested

Note:
- If you then close the “EnemyBehavior” and “TurretBehavior” tabs at the top and try again, it should allow you to join as the virtual player just fine.
