When the Mirror of Glamering was introduced on the Live Server, it was full of bugs and barely debugged.
Textures that were supposed to display didn't show up properly, and some parts failed to copy correctly.
There was even a bug where only the lower body wouldn't copy, resulting in the upper body showing the copied armor while the lower body displayed the Rags that appear when you're naked.
(Of course, there were also cases where the lower body was copied correctly but the upper body displayed Rags instead.)
Because of these copying errors, people who still have cosmetics from this time probably own various odd-looking Rags-like cosmetics.
There were so many different patterns of bugs that I regret not holding onto them.
The screenshot below shows the Stonemeld Plate Armor that failed to copy its colors properly.
Still had images left in the folder of screenshots taken long ago.
I searched through the old forums, but it seems the logs are no longer there.
If my memory is correct, there was a screenshot of a dwarf with a bright green upper body and only brown pants on the lower body.
Since there is still a bug with the Mirror of Glamering where the material colors of items are not copied correctly, it’s possible that there are still combinations where the copy doesn't work properly, and you might be able to create vivid Rags even now.
It might be worth experimenting with it the next time Lammania opens.
