Noticed a small debate in bazaar when someone tried to sell a fully evolved "An Ancient Quickworm" for 75k and someone pointed out it isn't evolving item because it lacked the level. I checked closely and indeed there seems to be 2 versions of An Ancientr Quickworm:

I extracted the ID numbers from these 2 versions. The top row of the number came from the ring (pictured left) with displayed "Evolving: Level 5/5 0%" and has 104205 before the ID number while other ring were all zero before the ID number and didn't have level displayed at all. I wonder if the extra number were the XP gained to level up? And where did the non evolving version drop???
