Help! My world is full of weird balls and I don't know where they come from [SOLVED]

[Superjoeyman]

Agh they're cheap so the AI keeps making them but they're so weird, they make weird slurping noises sometimes eugh.

Help me please, I need to know what NewGRF these come from so I can delete them from my 1850s era game.

Any help is super appreciated.

These vehicles are a part of the "Famous Cars" NewGRF.

If ever you want to know how to remove a NewGRF from your game, in this case Famous Cars :

1. Make a savegame, we don't know what could happen.
2. Sell all vehicles from this NewGRF.
3. Open the console, and type "stopai [number of the company]".
4. Type in the console "set newgrf developer_tools 1"
5. Go in NewGRF parameters.
6. Double-click on the NewGRF.
7. Click on "Applicate changes"
8. Since you have done a savegame, don't worry about pressing "yes".
9. Wait a little, it's done.

This is literally the worst thing you can do in this situation.

Quick way to fill your map with immobile bricks

Why is it the worst thing ? I always did that thing and i never had one crash.
Also, how can it fill the map with immobile bricks ?

[Gwyd]

The vehicle IDs are left blank, so the vehicles become bricks, or default graphics that have 0 for every stat. These are immovable and so are the tiles beneath them. Bad idea.

You only need to disable the parameter "Enable alien technology" in a new game...

And now...
There's no more free meat for them.

In case you didn't read, i wrote "sell all vehicles from this NewGRF".
Also, when you remove a vehicle NewGRF, it takes the name "<invalid vehicle>" and keeps its capacity, while it's sprite is replaced by an MPS Regal bus sprite. That is what happened for me though.

While having enabled "newgrf developer_tools", you can also change the parameters, exactly like in SilverSurferZzZ's screen. That is a better thing if you don't want to start a new game.

Thanks for the (occasionally conflicting) help everybody. In the end I just removed Famous Cars (turns out I had no idea what was actually in that NewGRF, whoops) and started over in a new game because I was only a couple of years in and haemorrhaging money anyway.

I'm going to counsel you : start with a train route between two cities of about 1k inhabitants, that will make money easily
