Title: Free road utopia created on map generation
Post by: Roboron on April 04, 2026, 07:06:37 PM
On map generation, a small neighborhood was created on one corner of the map, far away from any city hall. Even stranger: there is no roads! How are they supposed to move around without cars??? Insane!

If you join the Simutrans Public Server, you can see this for yourself. I have tried to recreate the map and the same happened again and again (with different buildings).

On reddit, there is a subreddit called /r/f***cars (I censored the word, but it's the "f" word in the name) that would probably love this. lol

I checked the buildings and they each belong to a different city. As such, some cities have their area going from (0,0) to (x2,y2) instead of (x1,y1) to (x2,y2). (As a side effect, what happens when such a city decides to build houses? Are they spread up over the map?)

This problem has existed for quite some time in the server game.

Sorry, I can't find the thread about it anymore.

The houses would be spread over the map, although in principle limited to a suitable location (near a road or next to a hosue).

Ah, geez, the way I play is with -freeplay on with a goal of serving every house/factory/etc. This would be an *adventure* of a map. lol. Little busses all over! :)

I have created quite a few maps an never got this so far. Are there any addons, like multitile buildings in your pak128?

No addons, vanilla pak128.

You can check the Simutrans Public Server map, and if you create a map with the same parameters it should happen again (it happened to me every time).

I created 25 maps and it did not happen even once. Sorry, cannot reproduce this.

I have had this happen before with pak192.comic. It seems to occur at certain densities of cities on map generation, but it has been a while since I was having the issue. Also therr has been the occasional very long or very wide city.
