Long reply:
What would you expect? It's a pre-alpha demo game. Purely to show technical aspects, ideas and vision they have. It's far from the stuff they actually wanted to release. Also you can't expect anything to work, you shouldn't even have it.

Yes, ''we'' experimented in the past even added original Unreal code to make it work but we came to the conclusion that JJ3 is to defunct to have something worked out with.

Just ingore it and enjoy what you have.

Moved topic to technical help, it's obiviously a request for help. Even tho I don't support this help request.
