Difficult to tell from the store photo due to the angle but I still think the front ones are shorter.
Measured mine and the back legs are around 2mm longer. If it is a miscast it would seem to be a common and very consistent one.
When I had a miscast Kaeris I got no email response from Wyrd, it just turned up in the post a few weeks later.
Re 2nd bit of last post. The Wyrd minis are quite delicate, ridiculously so in some cases. I reckon around 50% of the 40 odd figures I have brought have some sort of miscasting, usually a minor issue. only one was beyond fixing. But not the greatest casting out there.
