^ Same as him, I have no addon that has to do with cloaking.
Happens on TTT (Terrortown), haven't tested any other game mode, but not sure.
Now, I went to the link that Scout posted, and found MrPresident said this:
It sounds like you have a conflicting addon that might be doing something with the CreateRagdoll function.
Can you please try running ULX on a server with NO other addons and see if you get this issue? Preferably Sandbox gamemode.
Now for this, I do have some:
TTT Grav Nade and
TTT - Death Faker. Both of these create ragdolls.
Grav Nade: (Line 67)
local ragdoll = ents.Create( "prop_ragdoll" )
However, the Death Faker is slightly different, as it creates an actual corpse: (Line 95)
body = CORPSE.Create(ply, ply, dmginfo)
So I have a feeling that the Grav Nade addon is causing the conflict (at least in my case), and I will test the ragdoll without that addon later on when my server isn't almost full.
EDIT: According to that link Scout posted to the other issue about ragdolls, it seems to be happening on DarkRP as well (which is a Sandbox base.
