Battery Kit MK2 eeds productivity module mk2 to be crafted, but can be researched without.

It is questionable whether this is a bug. There are quite a few recipes that can be researched without technology X, but to be produced they require this technology. Especially the armors and their equipment that depend on higher levels of modules. Maybe you haven't researched the modules yet, but already have some (i.e. found in the ship wrecks) then you can craft these objects (like battery mk2) without researching the modules.

I wasn't sure about whether this is a bug either, but i just noticed it and thouht in case it's a mistake i post it. If it's not, this can be closed
