Do following changes :

• tempid in loop is not needed as your comment said.
• wpn var is not needed in CurWeapon event callback, also you don't need to check weapon at all since you add filter in register_event line.
• Also, put IsFrozen check before alive check as it doesn't use any native (curweapon and prethink)
• Func_Freeze doesn't need to be public
• formatex is not appropriated since you don't format anything, just use copy or directly assign string value.
• would be better to use client_disconnect than cilent_connect, also, check again for registered forward there.

Suggestion :
case 'A':
->
case 'A', 'a':
