CurWeapon event code is weird.
Suppose player A switch to c4, then the variable is set to that player index, and at the same moment player B shot with a weapon or switches to any weapon, then variable is set to 0.
I don't remember if bomb carrier is stored in my plugin, but you can look in it, or in VEN's tutorial on bomb scripting.

Also, you should make the plugin more dynamic so it could support any map.
