I've been having problems with the beta grenade.
1. The Explosion looks good, but it does not work for NPC'S. Whenever a combine soldier trows a grenade it explodes with the default sound and default explosion effect (sometimes there is no effect at all).
2. It does not affect the environment at all. It does not push props away, it does not knock down turrets. This gets really frustrating, because I sometimes find myself not having any other explosives, with which to take care of the turrets
I would be very grateful if someone was to tell me how to fix this.
