Getting an error with City Builder script

More information is needed, to help diagnose the cause.

1) What were you doing at the time the crash occurred (e.g. Loading a save game)?
2) What version of OpenTTD are you using?
3) What version of the script are you using?

There's probably more that's useful, but these are a very good start.

That's a know issue with Aphid's city-builder: viewtopic.php?p=1174481#p1174481
Unfortunately this script is no longer maintaned so no official fix have been released. But there is a some, supposedly fixed, version down in that thread made by community member.
