block mass changes with build state
It defies the laws of phisics that a ship can GAIN mass if a welder partially builds blocks onto itself.
Perhaps make it so that armor blocks have varing mass dependent on thier build states. It does not make sense that a light armor block weighs the same with 1 steel plate in it as a fully build 1.
It would be nice to have a way to create "skeletal" ships that use placed armor blocks to create some sort of lattice or framework that is super light.
