A fellow blenderhead called Jack-Jack informed me that the actual blend file for the project ‘The Other Day in The Forest’ was in fact corrupted. It was missing some external data and didn’t render correctly.
Thanks to Jack-Jack for bringing this to my attention.
A new version is now uploaded, which should work now correctly. You can download it directly from here.
I apologize for any inconvenience this may have caused, but then, until now nobody has complained :).
