There is an issue with second SMG. Helmet does whatever it wants to.
Also At-Rocket has "body" shown on DecayBoneAlternate animation, although I am not sure if this will be an issue in-game. Same with LMG, Mortar and SMG.
Also LMG has muzzle flash underneath bones in DecayBone, although this probably wouldn't show in-game.
And sniper... Is kinda using the wrench wrong. Well, not the wrench itself. Just... Look at StandWork animation. He is swinging his rifle like crazy.
That is what I found in last 10 minutes.
There is more.
Sapper now has the same issue as Sniper earlier.
