Good to know it is working in yours Dave, it is possible I messed something up -- were there a couple of versions of 4.1 out there?
I always make backups of the original files, I can email my export_descr_ancillaries from patch 4.1 to you if you would like to see it?
I have searched it for castle_town, agar & barcelona when I didn't get a Title for those, just to see if one was in there that I wasn't triggering.
I didn't find one, so I just copied a title from another city and modified it, plus added a text for them as a quick fix.
That is why I make backups of the original files, just in case I mess it up...which I did several times on Castle Town, I first had it as 1 word and it didn't like it etc...
**Another possibility is that a city name is referred to under a different name in the export_descr_ancillaries? --I have just noticed that is the case with some settlements in PDER...
It was maybe just that I failed to trigger the ancillary for some reason?**
