The static spawn of this mob next to the Lady Dirulia is nowhere near level 45. Consistently light blue to my level 51 BST. I don't know if there are others that are higher level. Some of the other level ranges are a bit suspect here too. The Dock Guardians are currently a mix of light and dark blue, but the boat engineer (another static spawn) is still dark blue, so the level on the boat engineer seems a bit low (listed as 37).
