Steps to reproduce:

1. Open attached project
2. Open 'Test' scene
3. Play the scene
4. In the console, notice that the test succeeds (Creates server, client and connects the client to the server)
5. Stop the scene
6. If you run the scene again after that, the test will fail two times in a row (usually hangs when trying to client to server)
7. After those two failed plays, the test succeeds everytime
