Sort of a thin report from issue tracker but Unity was able to reproduce in several revs. It is in the Active state but I would guess that there won’t be much effort since it was not reproducible in the latest rev of 2017.
Cheers.

Asset and Scene Management-Aug 15, 2017-Priority: 7 Not yet prioritized for a release-Severity: 1 Crash or major loss of functionality
To reproduce:
1. Open the project, attached by the user (New Unity re-try wo bts.zip)
2. Open the “TestScene_Tutorial3Complete” scene
