Checked your vessel in desperate search of solutions to somewhat similar problems while building mine. It is very well-built, loved the whole second deck (although D1 and D3 somewhat lack decor and look not so excellent).
There is an issue though, the lift seems bugged and does not respond to calls from D2 somewhy.
Also, you can decrease the amount of inner ship remotes by implementing timers for deployment and folding stages of its mining arm.
