well in .31 the button was still there, but now they can't clear forest OR jungle. I know Kael did something to get the AI to recognize that it won't destroy forest when it improves, but still, not bieng able to clear jungle is the part that is annoying me. The not clearing forest I can live with, it's the jungle part because they give the same resource output as a tundra tile. So it atually harms productivity to leave the jungle in.
However, I'm trying to find out whether this is intentional or not.
If it is intentional, then there needs to be some other way of removing jungle besides worldbuilder and using blaze, or make the jungle tiles more productive.
