Please allow productivity modules to be used by rocket control unit
In 2.1 productivity modules support needs to be specified explicitly, by setting
allow_productivity = true
in the recipe definition
Adding it did help me
{
type = "recipe",
name = "rocket-control-unit",
energy_required = 30,
enabled = false,
categories = {"crafting"},
ingredients =
{
{type = "item", name = "processing-unit", amount = 1},
{type = "item", name = "speed-module", amount = 1}
},
results = {{type = "item", name = "rocket-control-unit", amount = 1}},
allow_productivity = true
},

Thanks for the report, this is fixed in version 0.2.1.

I only started modding in 2.0, so when I copied the recipe definition from the 1.1 files, I had forgotten that in 1.1, productivity "permission" per recipe is defined as part of the module, not the recipe.
