I assume you changed the "Event Percent Chance Low/Medium/High" settings in Settings.txt. You might want to change all 3 to be 100%, just to cover yourself on game setup (i.e., forget to change event probability). BTW, since the default values are 5, 10 and 25 respectively, either the numbers are in tenths of a percent (unlikely, given the error message you encountered) or the game only checks for events at certain times (say, once per 10 turns). Otherwise, events would already be happening at a pretty fast rate.
