Assertain Failed: sceneId <

Whenever I try to load/reload my game, except when starting the game from the desktop, I get the following error (generated through Windows):

Assertain Failed: sceneId <
_scenes.size()(C:\rb\ihome\root\SH-OB-BUILD\stonehearth\source\horde3d\Source\Horde3DEngine\egScene.cpp:1505)

Loading throws this error (regardless of what save it is), the game crashes, and I have to restart back into the save.
