I took out the "deafen" sound feature because I have gotten numerous reports saying that after a while, it just keeps deafening you forever. I don't know what could be the cause. Trivial feature, un-comment out the lines if you still want this feature, or just don't download it.
It doesn't deafen me forever.
But then, most people don't continuously get hit by flash grenades. I think if it deafens you forever after a while, that is more realistic as multiple flash grenades will probably permanently damage your hearing.
Anyways, we need a normal explosive grenade that is not spammable nor has a huge explosion. Think you could do that?
