As the title says, the Gnezdovo Helmet and Byrnja Armour have display errors. Which is a shame, because they look cool and make a nice change from the usual mid tier armours. The Gnezdovo, despite being open faced like my Sarranid Keffiyeh Helmet, doesn't actually show my luscious man beard. the armour has an error with the left leg alignment which makes it protrude oddly when you stand still. making it look like your leg isn't joined to your thigh as the knee is way off.
I guess they're not massive issues, but they're pretty easy to fix. The armour just needs sorting out how it's been rigged / skinned.
