It's behaving very strangely. Although all the library's openings and paths are synced, it seems some aren't. The one I was trying earlier, which I linked to, started working, and I don't understand why. Now I'm trying to load others, but some work, and others don't... I just don't understand. I'll leave you with one that can't calculate the path at the moment. Could it be that I'm doing something wrong?
