[Solution]
I manually edited IDResolver’s ID config file. There were several items using ID 4168, marked from the RP2 module for Wireless Redstone (Chickenbones edition), probably due to me using an outdated version of the module (the current one is in a 404 link right now, sadly). After moving 9 items to ID 4169+ all was solved.
Now to re-make the logistic autocrafting system (because of the change on IDs)… XD

The game works, I checked it, the problem happens when I look in the direction of where I have a factory with tanks, three refineries, six iron generators (using fuel), and some logic gates.

The world was made a few weeks ago, and the only problem thus far has been low FPS (I have too much stuff going on there).

Edit: I checked on other newly made world that I have an additional problem: All BC gears (wooden, stone, iron, gold and diamond) are now fuel buckets in the recipes (and the fuel buckets can be made with the gears recipe). While the fuel bucket is using ID 4168, I cannot find where to change it to make it work (I ran into a similar problem with Mystcraft, but I found what file to modify).
