Adds massive cargo ships to the game, that function similarly to trains. Also adds deep sea oil, oil platforms, tanker ships, train bridges and other water based content.
We believe this occured when someone tried to deconstruct a ship with bots:
Error while running event cargo-ships::on_tick (ID 0)
LuaEntity API call when LuaEntity was invalid.
stack traceback:
cargo-ships/control.lua:217: in function <cargo-ships/control.lua:211>
