You unfortunately built this so it isn't in the grid properly, also has an issue where it gives me an error and says the door needs to be between 2 hulls despite being inside my ship. (As I'm writing this review I'm also playing the game, and after replacing the door the error went away, so my best guess is that because I placed the door outside the sub and moved everything in to try and fit it in the grid properly, when I moved it inside for some reason it was still registering as being outside the sub I guess) Thankfully the grid thing is fairly easy to fix, just had to snap the door into place and move it a bit, then moved the water detectors with shift+LMB to get them aligned properly followed by doing the same things with the motion sensors. For the work it took to properly set up the door I sure hope it does what it says lol, seems fairly legit though after seeing the wiring.

can this be rewired with a hatch and still working?

cool mod. i made a submarine with this
