Version of OpenTTD


Expected result

When using a NewGRF industry set which does not define a Mail cargotype (Action0, Property 18 = 02) or have a cargo in the typical mail cargo ID of 2, the Town GUI does not list the amount of Mail produced and transported last month.

Actual result

The GUI displays an amount of "Nothing" produced and transported last month.

(Note: It appears that the game is still calculating mail generation based on the mail multiplier house property, which displays as <invalid cargo> when I use the tile inspector on a house. I'll create a separate issue for this).


Steps to reproduce

  1. Use an industry set which doesn't define a Mail cargo, like Minimalist Industries, attached:
  2. Open the Town GUI for any town.

As I also commented in the other issue, in my opinion it's the NewGRF that's faulty when it undefines one of the core cargo types the game is built around.
