perhaps it can be fixed by adding a hand position adjustment relative to the weapon. or simply disable hands render in options

Based on previous reports, this should be caused by some mod conflict. It's not clear what the exact list of mods is

in game i have only create, ad astra and mekanism with this type of armor. + embedium with additions

Can confirm. Weirdly the bug doesn't exist in 1.0.1 for me, it only started with 1.0.2

fixed, will be updated in next release
