I have write some mod, create recipe run game, and play with it.
Now I want modify it and add to technology tree. I do this and problem was appeared.
When I start new game item require technology first and recipe is modify.
When I load old save, item doesn't require technology and recipe use old materials.

Any clue what to do with this?

the title tells me what you need is this:

And with the text I think that what you need to do is to reload the recipes in old saves
To do that you need to use:

game.player.forze.recipes["the recipe name"].reload()

Already done it by creating migration file in mod, good to knew alternative.

Code: Select all

game.player.force.recipes["the recipe name"].reload()

This is better than Because soon(er or later), we will start modifying recipe of players (technology to make some recipes cheaper for example).
This way you would revert all these kind of changes.
