I've created a trigger with "On Gold" in 2.0.7v and tried to make it work. It seems if "Cumulative" is checked (like in the picture below) the whole trigger won't start. Unchecking cumulative will make that trigger work, but it's effect is not what I wanted to achieve with that script of course. I set starting gold for 500.
