therother,

Yes, I started a new campaign each time, because I suspected that the effect would only apply to new campaigns. I had forgotten about the fog of war tweak. I did however, have at ~25% of the total Med. within my field of view and ~50% locally. I never witnessed a storm. I did see Etna erupt in 263 B.C. once.

I suspect that either the "at sea" syntax is incorrect in CA's file (or unsupported and instead hardcoded or scripted), or that the max frequency is 1 per year and is applied/distributed to ALL sea tiles. I haven't counted them, but this could make the probability of an individual tile or region ever getting a storm as being rather rare. That was why I tried 0.01. It is also limited to winter, with Floods on land limited to summer. It is still clear though that storms are rarer than hen's teeth and about as relevant in the game mechanics.

There was another file or two that has events listed, like an Etna eruption, an earthquake, and a flood all on specific tiles.

My fix right now is to eliminate all Roman ships from the descrip_strat file at the start of the campaign since Rome had no navy in 270 B.C. I also got rid of Gaul's boat. I've also made all ships two turn builds or greater (just made the 1's into 2's, and left 2's as 2's, 3's as 3's.) That should slow down the silly naval buildup.
