Lua Script error in "Iron Hand"

[Eboreg]

Just as the title says and I managed to pin down what's causing the error. The "Game_HourlyActions" Event action calls the "WeatherReportIsDue()" function first thing which is a massive problem because it doesn't exist in this scenario! I looked over the entire "LuaInit" Event action and was unable to find it. I understand that you're somewhat anal about receiving save files so I have attached the scenario file that comes with the base game.
