Error while loading recipe prototype "steam-engine-big" (recipe): Difficulty expensive: Value outside of range in property tree at ROOT.recipe.steam-engine-big.expensive.ingredients[2][1]
Modifications: Whistle Stop Factories
I am having trouble replicating this issue. Could you try these two steps:
First, make sure you've updated to 0.0.2. It fixes some mod related issues.
Second, if you're still having issues, please provide a list of mods you are using (One way to do that would be to find the mod-list.json in your mods folder, open it in notepad, and copy the contents into this discussion)
when I looked into that, it seems that multiplying ALL the recipes by 50 is what causes some issues. For example - at Space Industry mod, latest tech adds recipes with 10000x of something to make one container, multiplying this by 50 means getting over max value.
Not reporting any bug, just sayin what I found out :)
