Problem with PediaIcons.txt

[CKayote]

I added some new stuff to my conquest.biq, and now I get this (see image) when I try to start a new game.
Any ideas?

Make sure that your edited sutff has a civilopedia entry value, and that the corresponding ICON key is in pediaicons.txt

If you don't want to make up your own entries right away, you can "borrow" the entry for another improvement -- just type in the appropriate entry for the improvement of your choice, and it should work just fine. Just be sure to use a wonder entry for any new wonders, or the game will still crash.

IIRC, I always used The Internet for all improvements (wonder or not), because it made an extremely obvious reminder in game that I hadn't yet "finished" that particular improvement.
