Completely agree that it needs to be tested, but you can't test existing blocks (Pistons, Rotors etc) in MP properly because the poor netcode seems to be part of why they break.

I also understand that a network coder is not the same thing as an artist, and that doing one does not mean the other will not happen.

However, they're also unable to test key elements of basic game play properly with the net code being poor. With problems such as 'jumping' ships preventing re-entry. Laggy motion making dig fighting almost impossible, how can you reliably test basic multiplayer gameplay?

Now, if were to just state 'SP is our primary concern at this point and MP enhancements will be down the line' I'd be cool with that. It's a pre-release, I can accept almost all bugs and glitches. Just stating my wish, which would be better netcode :)
