I've looked at comments and a few threads here and it doesn't sound like the mod is entirely stable, but I'm still not entirely sure. I've wanted to try out the mod since I like the idea of being able to craft your own equipment and such...
What are your experiences with the mod? Does it work well, or are there still some issues?

Also, is this mod safe to add to an existing save? If I do that, is there anything I need to look out for?
