Factorio Forums

I am a freshman in Fectorio..
I have installed the Bob's Mods correctly,is the mods available to the old save?should i start a new world?

The mods have been built in such a way that they should work perfectly fine in old saves.

For best results, it is recommended that you do start a new world, but this is more so for issues like changed recipes, and a lack of the additional resources.
