Upon generating a new map with pak128.Britain (Standard Simutrans), the largest city on the map ran into trouble, possibly due to climates restraints. The city has 20 000+ inhabitants of which almost 19 000 is homeless (and unemployed). First building built was a residence...
I am not sure if this is related to the pak (lack of city buildings for difficult climates) or the game engine, or if it is even a bug....
Here is the city dialog:

There is a screen shot of the map at http://simutrans-germany.com/files/upload/homelessville.png (http://simutrans-germany.com/files/upload/homelessville.png)
Almost certainly due to limited choice of citybuildings with the timeline on (I ****ume your game has the timeline on?). As far as I know climates aren't a factor in pak128.Britain citybuildings (not yet at least). The main issue I think is that there are no industrial citybuildings currently for that point on the timeline.
Solution: draw more citybuildings. Volunteers? :)
