Here is the first version - Code is clean, no errors. I may of missed a few elements because the entire default UI directory was tossed into your UI folder (Incorrect way of loading UI's) So I was having a hard time comparing what was original files and which were custom.
As i said parts added to it from multiple UIs. only thing off was the window selector. As you can see it blanks out the unused buttons. So for this game should be there just only a couple buttons showing.
Never underestimate the potential of human density.
