Tried using it a few times but as soon as the mission spawns with it, while docked, it instantly breaks and loses most of it's outer hull and sinks to the bottom of the map.

i love it but dont use it do to how poorly my game performance is when i use it.

Poor electrical engineer, always repairing junction boxes

There is second sonar under the command table that can find the mine easily! Very useful!

For the creater：
Is it possible to reduce the lag? I love the sub!!

How could i set the shuttle battery? It's low battery supply as i detach the shuttle.

Something fun my friends and I came up with was a stealth button for the submarine. A button that toggles off ALL lamps, coilgun and railgun lights, and searchlights, making the ship pitch black. It shuts down the reactor and de-powers the fabricators and deconstructors. It reduces engine power by 80%. This way the ship is silent to sonar and very dark to visual, and makes molochs unable to find you, for example. It's super fun to put the ship in stealth mode and fire a torpedo at a helpless moloch! I'd recommend adding it :D

This sub lags my pc to high hell lol. My suggestion is to get rid of the door sensors and maybe get rid of the useless signs such as the "for sale" thingies. Also, If there is a version of the sub with absolutely no loot (no coilgun ammo or items in it), that will be fantastic. Biggest problem is the horrendous lag the sub tolls on the pc
