Wow thanks steejo.

Perhaps you can ask arumba to upload it along with his modpack on his website? Not insinuating anything, just thought it might be helpful

I think it does not work properly with portable roboport. When i upgrade stuff, the bots from my personal roboport just stands on the spot where an item is designated to upgrade.

-Edit-

Ok nevermind, the error is caused by having not enough bots removing the items on the belts... apparantly that's ...
