Really love the mod! thanks for making it! I did get a bug:

So biters got to my oil rig and destroyed it, it crashes the game. I am using alot of other mods, "Noxys Swimming" allowed the biters to get near.

It gave this pop-up error and then exits to the menu:
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>

thanks for the report. possible that i did not plan for that case, will look into it and try to fix it for the next update

should be fixed now
