[devel-new-2] Crash when saving after removing a town

[Rollmaterial]

If a town has been removed during the game, saving crashes with weighted_vector_tpl<T>::index_of() - not contained.

I cannot reproduce this error, but I have found and fixed an error relating to deleting cities which might be connected to this. Are you able to re-test?

[Rollmaterial]

It still occurs. Maybe the town needs to be connected with a stop. Otherwise try with the saved game form my last report about way upgrades.

[jamespetts]

I am still having trouble reproducing this. Which specific town did you delete? I deleted Kettering without difficulty when saving afterwards.

[Rollmaterial]

I get it when deleting Notting Hill.

[jamespetts]

Do you get it when you delete Kettering?

[Rollmaterial]

Do you get it when you delete Kettering?

No

[jamespetts]

Thank you for that. I think that I have now fixed this: would you be able to re-test?
