This required mission is so long and difficult that after investing 8 hours in multiple attempts i have succeeded even once. Between the constant server disconnects and bugs it just isn't worth trying any more. This last time, the server disconnected, but it succesfully reconnected and put me back in, great!, I thought, until I realized it had put me back in behind the area just past the piston where the modules had already been used and there was no way forward snd the gates were all closed. Great puzzle logic there.
