Game Modes: player doesn't have reliably acknowledge about other player's gamemode

```
[core] addons/core/lua/core/gamemode/sh_gamemode.lua:90: attempt to call local 'CanTakeDamage' (a nil value)
  1. CanTakeDamage - addons/core/lua/core/gamemode/sh_gamemode.lua:90
   2. unknown - addons/core/lua/core/gamemode/sh_gamemode.lua:94
    3. unknown - addons/lib_shook_git/lua/includes/modules/hook.lua:313
```

Probably, just need to replace NW2 with NW
