'copper-tungsten-alloy' does not exist, hit a snag on productivity-module
not sure if this is an issue with your work or my setup.

What fashion can this recipe be in?
May I ask for your list of mods or your save game?
The fact is that the mod does not create new recipes, it adds its own based on existing ones in the game.

Or copy and paste the error message here, it will be easier for me to understand

Version: 0.7.0
Date: 20. 12. 2019.
Bugs:
- Added compatibility with extendedangels

The extendedangels mod removed some of its recipes from the list of productivity modules, and the stoves tried to find and insert them. Everything should work now.

thanks a bunch!
