Hello. I've got next problem: some model replacements making my server unstable(it crashes after first round start). I am not sure why it happens. As example: i download match_m249 machinegun from fpsbanana.com, upload all files(materials and models), rename v_match_m249para.* to v_m249para.* and replace model name in v_m249para.mdl(from v_match_m249para.mdl).  Then, by analogy with the files doing the w_match_m249para .*. After that i change model names in shared.lua(orangebox\garrysmod\gamemodes\ttt\entities\weapons\weapon_zm_sledge\shared.lua), and finally i add all files to resources.lua like that:

  --m249
    --models
      -- v_ models
        resource.AddFile("models/weapons/v_m249para.dx80.vtx")
        resource.AddFile("models/weapons/v_m249para.dx90.vtx")
        resource.AddFile("models/weapons/v_m249para.mdl")
        resource.AddFile("models/weapons/v_m249para.sw.vtx")
        resource.AddFile("models/weapons/v_m249para.vvd")
      
      -- w_ models

After that client will download model && materials. But when i start server and start round i see next messages:

Weapon/ammo placement script found, attempting import...
Reading settings from script...
Removing existing player spawns
Removing existing weapons/ammo
Importing entities...

then server crash with access violation. Can anyone help me?
P.S That happens only with some weapons.

[li]Deagle[/li]
[li]Huge[/li]
[li]Knife[/li]

Maybe some other weapons(not sure yet)
