It just crashes out whenever I go into certain cities (most of them), or go to the "domestic adviser". I'm not sure why this would be; I've only added techs, buildings and units since the last installments, and I've checked and double checked to make sure I haven't missed out any 'pedia entries, etc. I would assume it is a problem with citizens, due to it only effecting the "larger" cities, but I haven't actually altered any citizens since the last update.

Does anyone have any idea what could be causing such an error?

Wish I could help as have the same problem in the same areas with an entirely different mod ... I have looked at the internal error codes getting but have yet to figure them out. In one case had a memory overflow, but in the others didn't. In general I do not get the msg you display just a drop to the desktop, so it is possible you error is different then what i run into with large cities and the adviser screen (usually the F1 dude)

If you have a unit entry named incorrectly (i.e. PTRO instead of PRTO), the game will crash like that.... ditto for building entries (BDLG instead of BLDG), so be sure to go through your civilopedia.txt file and your scenario .BIQ file to make sure you haven't made any such spelling errors.

I'm afraid there aren't any spelling errors with either the units, techs or buildings which I added... :(

Sorry to double post, but I (kinda) worked out the error. I set ALL extra citizens (that's the "Entertainer" and such) to require a dummy tech. The end result; I could now both enter all cities, and go into the domestic advisor!

BUT there is a problem; the citizens have not been changed at all during development, so I don't know what could be causing this sudden problem...


EDIT: I think I get it! I've increased the eras to 4, whilst not doing the same for the popheads file! I knew it would be something simple!

EDIT 2: Yup, that did it! :D
