Hrm, that's wierd - when I tested, I invited one of my freeport alts using my Qeynos main, and it worked. I'll take another peek at it, make sure I didn't misplace anything.
No clue as far as the crafting window, I didn't actually touch any of the code for that, and don't even have it mod'd - the only reason it looks any different, is the background texture's were replaced in the images directory. I've been thinking about modding it though, I really don't like the way the pristine cobalt recipe names warp too far up when they "word wrap" down to the next line.
That crafting window code is just really a pain to work with in UI builder, so it may take me a bit of "trial and error" in wordpad to get something better put together.
