A modder's guide to errors

[Aradan]

My guess is that you run out of memory.

Unusual error to add to the list:
I had a campaign load CTD with the following error: "Generic error: insufficient memory to load requested texture set"

The cause was that one of my strat map banner DDS files had not been saved with DXT5 compression or with mipmaps generated. Fixing that got rid of the error.

During process of modding Extended Cultures 5, I encounter a few ctd during ai's auto-game. I tend to get around 1-2 random ctd which could not repeat (due to game is not breaking, it still able to continue from save game) and rarely get ctd which game just close without any message or warning (just automatically close as if nothing happen) but I also could not emulate that close without warning message as well.

Could anyone explain to me about what could be cause of random non-gamebreaking ctd? and what could be cause for game to close without any warning (no message, no order, just automatically close without warning)?
