If you haven't used the Hues editor in Fiddler to create new Hues, you probably haven't experienced this particular bug yet. Here is what is happening:
In the Hues editor, you have the top line with all the individual hue boxes you can change. If you change one from the default black (0, 0, 8), to anything else and then click on the box you just colored, the values will change, as will the color.
Lets say you're looking at a Hues.mul from another shard and you want to copy some of the Hues to your own Hues.mul. So you open Fiddler (twice) and point each instance to the different Hues.mul files. Now you can compare hues, side-by-side. Double click on the Name/HexID to the right and it will open the Hues Editor. You can click each hued box from the Hues.mul you are copying from as you change those boxes in your own Hues.mul. This is where the bug creates a problem, because every time you click to select a new box, the values have already changed from what they originally were. I thought it was just the box being "highlighted" to show you had that one selected, but that's not the case. The values are being changed when you click a hued box (hued anything other than the default 0, 0, 8). I have not tested to see if this bug exists in previous versions, this was just from v4.6
