Editting a Mod Recipe

[Ambition]

I was enjoying an Industrial Revolution 2 playthrough until I wanted to automate wood. I didn't want to make 400 buildings just to get 15 wood a second.

So I opened up the mod in %appdata and found the line that I wanted to change for the forestry building. Recipe time was 8000/40 and I changed it to 1000/40. But doing so removes the mod from the modlist and forces an update on me.

Hoping someone is willing to explain how to do this change, thanks.
