Turn down fires in Update 2?

[Kuplo]

Does anybody know what needs to be modded to turn down the occurance of fires after Update 2 has been installed?

I assume it's been adjusted in the game with update 2 because I've been playing my first new game (strategic mode) and within 1 hours time, I've had no less than 6 fires. Fires at buildings that are NOT more prone to catch on fire or at least their building card doesn't say they are more prone to catch on fire.

So I'd like to turn down the frequency of the fires if at all possible.

A hint will likely do (like which file, fire possibilities are contained in).

Thanks,
