In the meantime, I'll check the virtual table offsets...
It's just weird that it doesn't crash with our servers... although maybe we're not executing the command(s) you are...
Also, the gamedata only handles 4 actions:
SetModel
Weapon_Drop
Respawn
RemoveAllItems
I tried all 4 of those and no crash.
If you could narrow down the command that crashes the server that will help out tremendously... perusing 2,441 lines of code that isn't mine to begin with doesn't sound like my idea of fun...
