Ok, the main reason unlike what the others say is.
Everytime there is a update to JO or any mods the stats stop working. The stats guys have to write new code for the updated game and it takes time if it ever comes out? It's alot of work for me to keep tabs on what's what on it.
For example the link you provided would not work as we play JO IC mod and that was only for JO. We would need a version for JO IC mod and the version we play.
Sonce the updates have slowed, if someone can find the correct version, I can look into it.
