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.
Thanks for the report. I see this in my game as well. The GUI is messed up for ship engines but not boat engines or normal locomotives. I have no idea what could be causing this, will investigate.
Width problem is because of the fuel tab I believe.
Strangeness at the bottom is a base game bug caused by the Train Groups relative GUI: https://forums.factorio.com/98151.
I already uninstalled the mod (I'm already using 350 mods!) But I remember that the ships have a bunch of slots, plus the slots for spent fuel, that another mod that I'm using added to all vehicles!
Latter I'll try to reduce the number of slots to see if this fix the problem!
