i want to increase the amount of meteors. I have the command <gameplay_modifier type="MeteorRisk" param="High"/> but the game tells me that its wrong. needs to be none, low, high, variable..... If I try "high, 10.0" error, If i try "high" eroor, If i try 10.0 error. I need the meteors frequently. I have looked at all the challenge xml files and they dont show what i need except for windstorms and that uses ythe "10.0" modifier. So what am i doing wrong?
