As with any patch- some mods will break, and some will be fine- but you are able to choose to remain on whatever
patch you are currently working with and don't need to update. Steam has an option to turn off auto-updates, and
so do the consoles, so they will not update until you manually do it yourself.

You won't be able to use any of the mods that are updated for patch 8, but you can continue your playthrough until
you are ready!
