Floating SWEP + Model Issues

[Sonic2756]

I'm currently using some workshop SWEP's on my TTT server. They're "ports" of CSGO weapons + skins. I'm having two major issues. The first being that the weapons float when dropped for anyone but the person who dropped it (sometimes it works properly, but most of the time it's an issue) , the second issue being that certain custom models don't show the weapon in the players hand and throw the following error (the weapon_bizon_csgo just being an example, all of them throw this error for their respective weapon):

[ERROR] addons/csgottt/lua/weapons/weapon_mp7_csgo/shared.lua:158: attempt to index local 'hand' (a nil value)
1. old_DrawWorldModel - addons/csgottt/lua/weapons/weapon_bizon_csgo/shared.lua:158

I'd greatly appreciate any help. Code from one of the SWEP's is below.

local soundData = {
    name 		= "Weapon_Cbizon.Clipout" ,
    channel 	= CHAN_ITEM,
    volume 		= 1,
    soundlevel 	= 80,
    pitchstart 	= 100,
    pitchend 	= 100,
    sound 		= "csgo/bizon/bizon_clipout.wav"
}

sound.Add(soundData)

local soundData = {
    name 		= "Weapon_Cbizon.Clipin" ,
    channel 	= CHAN_ITEM,
    volume 		= 1,
    soundlevel 	= 80,
    pitchstart 	= 100,
    pitchend 	= 100,
    sound 		= "csgo/bizon/bizon_clipin.wav"
}

sound.Add(soundData)

local soundData = {
    name 		= "Weapon_Cbizon.BoltForward" ,
    channel 	= CHAN_ITEM,
    volume 		= 1,
    soundlevel 	= 80,
    pitchstart 	= 100,
    pitchend 	= 100,
    sound 		= "csgo/bizon/bizon_boltforward.wav"
}

sound.Add(soundData)

local soundData = {
    name 		= "Weapon_Cbizon.Boltback" ,
    channel 	= CHAN_ITEM,
    volume 		= 1,
    soundlevel 	= 80,
    pitchstart 	= 100,
    pitchend 	= 100,
    sound 		= "csgo/bizon/bizon_boltback.wav"
}

sound.Add(soundData)

local soundData = {
    name 		= "Weapon_Cbizon.Draw" ,
    channel 	= CHAN_ITEM,
    volume 		= 1,
    soundlevel 	= 80,
    pitchstart 	= 100,
    pitchend 	= 100,
    sound 		= "csgo/bizon/bizon_draw.wav"
}

sound.Add(soundData)

That attachment doesn't exist in that weapon model, then.

The solution would be to find the proper bone on the world model.

The custom playermodels I have work with the default TTT weapons. The custom weapons are what's causing the issue.

What bones do the default TTT weapons merge to?

Could also be that your server is missing the said models. ( For the floating dropped weapons issue )

I fixed the floating weapons last night with two lines. Just need to fix the weapons not attaching to models without hands. I know they function with default weapons, just the custom weapons don't work right because I can't find a proper attachment point.
