"Plant harvest yield" stat in scenario editor does nothing

[groovybluedog]

I've gone in to the scenario editor and made some changes, like global work speed, and plant harvest yield. In this case, the yield is 500% for testing so I could clearly see it, after noticing it wasn't working on a previous game, but with heavy modding.

I've just gone to plant something, on a map with no mods, to confirm my theory. When I use the dev tools to finish a plants growth, and a harvest is made, it only harvests the amount on the Wiki, for example 7 corn, instead of, in theory, 35, as it should be 500%.

Am I misunderstanding this stat or am I doing everything right and this is a bug in the game? Global work speed appears to work fine.

This is because the "Plant harvest yield" doesn't affect the yield directly, it gives you a chance for a completely failed harvest. So you always either get full yield or none. The chance for failing is 100%-"Plant harvest yield" stat and because the chance for failing can't be lower than 0, "Plant harvest yield" is effectively capped at 100%.
