Hi. 
Will get right to the point!
Item: ‘Dragonrider’s Harness’
(Mail, chest item).
This item has a tattoo look, however there is a very weird line on the lower back of the character when wearing this appearance. Regardless of race.
It seems very out of place, has a different color than the tattoo look, and even crosses some the lines with the (I assume) intended design. It really looks like a bug, and not like someone intended this to happen.
It is such a shame as it really ruins the whole idea to some point.
(Unless it is some sort of bad cover up tattoo to ‘erase’ the weird one, lul.)
Hope you fix it asap!
Cheers!
Cheers,
Gromuk
