A modder's guide to CTDs

[Dol Guldur]

No, all factions engage without error - it's just at *some* sieges. It occurs without characters present, and does not seem building related either. At other times these same cities can be taken without CTD. I have not had the CTD myself (nor can I duplicate it) but do from a saved game given me by a player.

IIRC, we were getting these kinds of CTDs with the Aedui because of a typo in expanded_bi.txt

We have not made changes to the tags/internal faction names so I do not think there is an error there.
