They are partnered with a server company so they can fix any server issues and the amount they need to run the game smoothly before beta, this is why they have modules to have heavy player load to check what they need to fix for beta, we are the mice in a experiment for servers:p

They want a release first quarter for beta and full game 2nd-3rd quarter-all 2018, no push backs confirmed as they are working for full games as wells as making the modules at the same time so thats why its taken longer for modules as they are not just working for modules only which is better as the game is being built quicker.
