Wait if it does then it should already work? The only thing that was leftover from GT5 when I did GT6 was the Tools, since those already used the System I wanted them to use.
Give me the Mod ID of Treecapitator then, that way I can fix it on my end. Also would be nice if you gave me your Treecapitator Config too, so I can add it to the Default Config Pack. ^^
