Git commit c5ccfc20e8265f92ca73e8714a42f8691d68d2c2 by Martin T. H. Sandsmark.
Committed on 20/11/2016 at 13:29.
Pushed by sandsmark into branch 'master'.

Don't crash/assert on trying to load session with invalid ID

Failing to find a ID should not be a fatal assert, the ViewManager
handles it properly.
