If you check my post back on page 49, you will see that it's now 3.0.6.1. I reenabled the warp bonfires option, and did what you just mentioned to make it work fully.
As for the item adder, I know it's not ideal, and I was trying to think of a way to fix that. But my coding style is so much different than Jappi's, that I'm not sure how to go about it without changing the whole item setup. It might be better to do it that way though, because it currently uses strings
way too much, making it very inefficient.
I just really don't want to steal Jappi's work and make it my own project.
I don't know of any way to be completely invisible. I have tried everything I can think of, but even if you have all your armor and hairstyle set to None, the game will still render your head.
I may have to start testing things with a friend though, because I never thought of the possibility of other people seeing something different than I do.
