Productivity affects vanadium powder recipe, which makes for a positive quicklime loop. I thought it was intended as the catalyst - the same amount of calcium from once imported calcite (cool idea) as quicklime, but productivity throws that off and I have to recycle quicklime. Maybe disable productivity at that stage?
Also I have two identical recipes for quicklime from calcite with Age of production installed, but only one works and machines do not accept the other, had to tweak the recipie in files.

I ended up tweaking the recipe to remove the calcite positive loop, in file "shchierbin\prototypes\recipe.lua" in result line for quicklime of vanadium-dust add (at line 76 as of 0.3.14) ", ignored_by_productivity=5" at the end, before the closing parenthesis, it should look like that

results = {{type="item", name="vanadium-dust", amount=2},{type="item", name="quicklime", amount=5, ignored_by_productivity=5}},
