This was a server crash, not client
- When I startup server now I get this crash... But I removed the blueprints folder from server and its all fine..

I've had a similar crash after making a blueprint. I'm not sure what the answer is, and I would really like to be able to access that save again.

It might mean that blueprints aren't yet implemented because it's a beta version. javax.management.RuntimeErrorException: NOT IMPLEMENTED
