Ok, thanks. I've found the descr_disasters.txt file (no need to unpack). Is it only necessary to disable floods or do I get rid of earthquakes, dustbowls, locusts, etc. too?

Also, is this a retroactive step - will it fix campaigns that are already underway that have bugged provinces?
i have only had problem with the flash-floods (after a flood, units in that province lose movement points) so that's the event i disabled. have not had lost movement points (and inability to build forts, border towers) problem since then. i started a new campaign though so i am not sure whether the changes are retroactive. i suspect, they are not. but you can easilty test that. disable the flash flood. reload the game and see whether you can build a border tower in the affected province.
