How to reproduce:
1. Open the project in the zip-folder "project_for_bug_report.zip"
2. Open the scene "Scenes/Swamp/Swamp_01"
3. Enter playmode and then exit it again. The canvas is created on start
4. Watch unity crash

Note: if when playing Swamp_01 scene, one disables or changes canvas (GameRoot->UIAnchor->FishODex->Canvas and GameRoot->UIAnchor->FishODex->ContentAnchor->MapContent->Canvas) render mode, Unity doesn't crash when exiting play mode

OR
1. Open the project in the zip-folder "project_for_bug_report.zip"
2. Open the scene "Scenes/CatchDisplay"
3. Without doing anything else - open the scene "Scenes/Swamp/Swamp_01"
4. Watch Unity crash

Both ways give the same stack trace in Unity 5.4
